[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pin stand and a method of manufacturing a pin stand board, and more particularly, to a pin stand and a pin stand which can easily stand pins, and the pins are easy to stand and inexpensive. The present invention relates to a method for manufacturing a pin standing substrate that can be manufactured in a single step.

[0002]

2. Description of the Related Art Conventionally, a pin setting jig has been used in which pins as input / output terminals are erected on a substrate main body to produce a pin erected substrate. . As an example, a pin stand jig 101 shown in FIG.
Is mentioned. This pin stand jig 101 has an upper surface 101
A and a substantially plate-like shape having a lower surface 101B and a large number of distal end insertion holes 102 penetrating between upper and lower surfaces. The upper surface 101A side of the distal end insertion hole 102 is chamfered to facilitate insertion of a pin. FIG. 16 (a)
16B is a plan view as viewed from the upper surface 101A side, FIG. 16B is a partially enlarged view thereof, and FIG. 16C is a partially enlarged cross-sectional view of the tip end insertion hole 102 taken along a dashed line in FIG. Is shown.

[0003] Using such a pin stand jig 101,
In manufacturing a pin standing board, it is usually manufactured as follows. That is, as shown in FIG.
The above-mentioned pin stand jig 101 is prepared, and its upper surface 101A is prepared.
, A large number of pins 111 are placed. This pin 111
An engaging portion 112 includes a distal end portion 113 and a proximal end portion 114 which extend from the engaging portion in a reverse manner. The diameters of the distal end portion 113 and the proximal end portion 114 are both smaller than the diameter of the engagement portion 112, and the length of the proximal end portion 114 is shorter than the length of the distal end portion 113. As will be described later, the pin 111 has a base end 114 inserted into the pin connection hole 122 of the board main body 121, an engagement portion 112 engaged with the pin connection hole 122, and a tip end 113 of the board main body 121. Lower surface 121B
It is erected on the substrate body 121 so as to protrude to the side.

Next, as shown in FIG. 17B, the pin 111 is moved on the pin setting jig 101 by vibrating or swinging the pin setting jig 101. At the same time, the air in the distal end insertion hole 102 is sucked from the lower surface 101B side of the pin stand jig 101 so that the pin 111 is inserted into the distal end insertion hole 102. At this time, the distal end 113 of the pin 111 needs to be inserted into the distal end insertion hole 102 of the pin stand jig 101 so that the proximal end 114 of the pin 111 can be inserted into the substrate main body 121 later. is there.

[0005] Next, as shown in FIG.
A substrate body 121 having a substantially plate shape having a bottom surface 21B and a bottom surface 121B and having a large number of pin connection holes 122 is prepared at a position corresponding to the tip end insertion hole 102 of the pin stand jig 101. And the pin setting jig 1 on which the pin 111 is set up
01 and the substrate body 121 are aligned.
The base end 114 of the pin 111 protruding from the pin stand jig 101 is inserted into one pin connection hole 122. Thereafter, when the pins 111 and the board main body 121 are soldered, the pins 111 are erected on the board main body 121.

[0006]

However, FIG.
As shown in FIG.
2. When the pin 111 is inserted into the
Although the three sides should be inserted, the base end 114 side of the pin 111 is actually inserted at a considerable rate. In particular, when the shape difference between the distal end portion 113 and the proximal end portion 114 is small as in the case of the pin 111, the proximal end portion 114 side of the pin 111 has a pin setting jig 101 at almost half the ratio.
Is inserted into the distal end insertion hole 102. When the pin 111 is inserted in the opposite direction as described above, it is necessary to pull out the pin 111 by hand or the like, change the direction, and then reinsert the pin 111, which requires a lot of time and labor. For this reason, the cost of the pin standing substrate has been increased.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and a pin setting jig which can easily set a pin with a fixed direction of the pin, and a pin can be easily set up.
It is an object of the present invention to provide a method for manufacturing a pin standing substrate which can be manufactured at low cost.

[0008]

Means, functions and effects of the invention are achieved by an engaging portion, a distal end portion extending in opposite directions from the engaging portion, and a base end portion having a shorter axial length than the distal end portion. A pin standing jig for erecting a pin having a base end side protruding therefrom, having a main surface, opening toward the main surface side, and positioned on the main surface side. Large diameter part
A tip portion that opens into the large-diameter portion and is located on the back side of the large-diameter portion, and a tip portion in which the tip portion of the pin can be loosely inserted into any of the large-diameter portion and the deep portion. With a large number of insertion holes, the large diameter portion, the maximum dimension in the direction along the main surface is larger than the maximum size in the direction along the main surface of the back portion,
The base end portion is freely insertable, the engaging portion is not insertable, and the depth to the opening end of the back portion is greater than the axial length of the base end portion. Tool.

When this pin stand jig is used for a pin having a predetermined shape having a distal end portion and a base end portion having different lengths, when the distal end portion of the pin is inserted into the distal end insertion hole from the main surface side ( Hereinafter, such insertion is also referred to as “insertion in the forward direction”.) In this case, the distal end portion can be inserted beyond the large-diameter portion to the deep portion. Therefore, without leaning too much,
The pin can be made to stand with the base end side projecting from the main surface. In addition, since the distal end portion is inserted to the back, even if the pin stand is moved or the pin on the main surface is dislodged, it is relatively difficult to remove.

On the other hand, when the base end of the pin is inserted into the front end insertion hole from the main surface side (hereinafter, such insertion is also referred to as “insertion in the opposite direction”), Since the depth of the large-diameter portion is greater than the length of the proximal end portion, the proximal end portion is not inserted beyond the large-diameter portion and into the deep portion. Further, in the large-diameter portion, the maximum dimension in the direction along the main surface is larger than that in the deep portion, so that even if the pin stands with the tip end side protruding from the main surface, it tends to stand in an inclined state. Therefore, when the pin setting jig is moved or the pin on the main surface is removed, it is relatively easy to come off.

For this reason, when a large number of pins are placed on this pin stand and the pins are moved, the pins whose tips are correctly inserted into the tip insertion holes, that is, the pins that are inserted in the forward direction, Then, even if the pin setting jig is moved thereafter, the state in which the pin stands without falling out of the tip end insertion hole is maintained. On the other hand, for the distal end insertion hole, more specifically, for the pin whose base end is inserted into its large diameter part, that is, for the pin inserted in the opposite direction, once inserted, the pin stand jig is then used. It is easy to fall out when you move it. Therefore, after such a pin comes off, the tip of another pin may be correctly inserted into the tip insertion hole.

Further, even when the pins on the main surface can be removed by air, a brush or the like, the pins whose tips are correctly inserted into the tip insertion holes (inserted in the forward direction) do not come off. The standing state is maintained. On the other hand, not only pins for which neither the distal end portion nor the proximal end portion is inserted into the distal end insertion hole, but also pins for which the proximal end portion is inserted (inserted in the opposite direction) into the distal end insertion hole can be easily removed. Can be

As a result, in this way, the pins can be efficiently inserted in the correct direction, and only the pins whose tips are correctly inserted into the tip insertion holes can be left on the pin setting jig. In addition, by repeatedly performing a plurality of cycles, that is, placing the pin, moving the pin, or placing the pin, moving the pin, and removing the pin in order, it is easy to correctly insert the tip into all the tip insertion holes. To make the pins stand.

Here, the material of the pin setting jig may be appropriately selected in consideration of the subsequent processing method (such as soldering, brazing, or press-fitting), the coefficient of thermal expansion, and the strength. High heat resistance and easy processing, carbon, machinable ceramics such as boron nitride, alumina,
Examples include ceramics such as silicon nitride, steel materials, and metals such as stainless steel. The shape of the pin may be any shape as long as the base end portion is shorter in the axial direction than the tip end portion, and the shapes of the tip end portion, the engagement portion, and the base end portion can be appropriately changed. For example, the distal end, the engaging portion, and the base end each have a substantially cylindrical shape, and also include pins having a substantially long cylindrical shape, a substantially elliptical cylindrical shape, a polygonal cylindrical shape, and the like. Further, for example, the distal end, the engaging portion, and the proximal end have completely different shapes, such as a substantially cylindrical shape at the distal end, a substantially elliptical cylindrical shape at the engaging portion, and a polygonal prism at the proximal end. Pins are also included.

The maximum dimension in the direction along the main surface of the large-diameter portion and the deep portion is defined as the maximum dimension of the portion of the large-diameter portion and the deep portion into which the tip or base end of the pin can be inserted. Say. When the bottom surface of the large-diameter portion is flat and parallel to the main surface, the depth of the large-diameter portion to the open end coincides with the depth of the large-diameter portion. In other cases, when the base end side of the pin is inserted into the large-diameter portion, the depth from the contact position where the engaging portion abuts to the opening edge of the back portion opened to the large-diameter portion. Refers to the distance measured in the direction.

The distal end insertion hole is formed as a through hole, or the depth of the distal end insertion hole is adjusted such that the distal end of the pin is inserted and the engaging portion is engaged with the large diameter portion of the distal end insertion hole. However, if the depth of the tip is set so that the tip of the tip does not reach the bottom surface of the tip insertion hole, the tip is inserted into the back of the back until the engagement portion engages with the large diameter portion. The inclination can be further suppressed. In addition, it is preferable that a gap formed at the time of insertion of the pin distal end portion is made small in a deep portion of the distal end insertion hole in a range where the distal end portion of the pin can be inserted in a loose fitting manner. In addition, the large diameter portion of the distal end insertion hole may be located on the main surface side of the back portion, and may be located on the back side of the main surface.

Further, in the above-mentioned pin stand jig, it is preferable that each of the large-diameter portions of the plurality of distal end insertion holes has a shape that is long in a predetermined direction among the directions along the main surface. It is good with the pin setting jig which is the feature.

If the dimension (for example, the diameter) in the direction (plane direction) along the main surface of the large-diameter portion is increased within a range where the engaging portion cannot be inserted, the base end portion is inserted into the large-diameter portion. In addition, the pins are more easily inclined and the pins are more likely to come off. However, when it is desired to reduce the distance between the adjacent insertion holes at the distal end, the distance between the large-diameter portions cannot be sufficient, and it becomes difficult to manufacture a pin setting jig. In the present invention, the large-diameter portion of the tip end insertion hole of the pin setting jig has a shape that is long in a predetermined direction. For this reason, the base end portion inserted into the large-diameter portion of the front end insertion hole tends to have a large inclination particularly in this predetermined direction, and is more likely to come off. In addition, since the large-diameter portion is long in the predetermined direction, the interval between the large-diameter portions can be increased except for the tip insertion holes that are adjacent in the predetermined direction among the adjacent tip insertion holes. Therefore, even when the interval between the distal end insertion holes is small, the pin stand jig can be easily manufactured.

Further, in the pin stand jig, the plurality of tip end insertion holes, which are adjacent to each other in the predetermined direction in the plurality of tip end insertion holes, are connected in the predetermined direction in which the large diameter portions are connected to each other. It is preferable to provide a pin setting jig characterized by having a long common diameter large portion.

According to the present invention, with respect to a plurality of tip end insertion holes adjacent in a predetermined direction, the large diameter portion is a connected common large diameter portion. Therefore, when the pins on the pin setting jig are moved or when the pins can be removed, the pins inserted in the opposite direction are more easily inclined in the predetermined direction, and the pins are more easily pulled out. Further, since the common diameter is large, the production of the pin setting jig becomes easy.

Further, a pin having an engaging portion, a distal end portion extending in the opposite direction from the engaging portion, and a proximal end portion having a shorter axial length than the distal end portion is protruded from the proximal end side. A pin standing jig for standing in a state in which the large-diameter portion has a main surface, is open toward the main surface side, and has a large-diameter portion located on the main surface side, and is opened in the large-diameter portion. A back portion located on the back side of the large-diameter portion, and both the large-diameter portion and the back portion are provided with a large number of tip insertion holes into which the tip of the pin can be loosely inserted. The large-diameter portion has a diameter larger than the diameter of the deep portion and the diameter of the base end of the pin, smaller than the diameter of the engagement portion, and the depth of the large-diameter portion in the axial direction of the base end. It is preferable to use a pin stand jig characterized by being longer than the length.

Normally, for example, the distal end, the engaging portion, and the proximal end of the pin are often formed in a substantially cylindrical shape, for example, due to the ease of processing. When such a pin is used, it is sufficient that the shape of the insertion hole at the tip end of the pin setting jig is substantially circular in cross section. For this reason, when forming a tip end insertion hole in the pin stand jig, it can be easily processed by a laser, a drill, or the like.

Furthermore, the large-diameter portion of the distal-end-side insertion hole is
It is preferable to provide a pin setting jig in which the engaging portion of the pin cannot be inserted, and the diameter of the large diameter portion and the diameter of the engaging portion are substantially the same. The larger the diameter of the large-diameter portion of the distal-end insertion hole, the greater the inclination of the pin when the base end portion of the pin is inserted, and the easier it is to drop out of the distal-end insertion hole. In the above-mentioned pin stand jig, the engaging portion of the pin cannot be inserted into the large-diameter portion, and the diameter of the large-diameter portion is assumed to be substantially the same as the diameter of the engaging portion of the pin. That is, the diameter of the large-diameter portion is widened to the extent that the engaging portion of the pin can engage with the large-diameter portion of the distal-end insertion hole.

Another solution is to provide a substrate body having a substantially plate shape having a main surface of the substrate and having a large number of pin connection holes opened in the main surface of the substrate, an engaging portion, and an engaging portion. A plurality of pins each having a distal end portion extending in the opposite direction and a base end portion having a shorter axial length than the distal end portion, wherein the pins are respectively inserted into the pin connection holes and stand on the main surface of the substrate. A method of manufacturing a pin-equipped substrate, comprising: a main surface, an opening in the main surface, a large-diameter portion located on the main surface side, and an opening in the large-diameter portion. A large number of distal end insertion holes having a back portion located on the back side, and the large-diameter portion has a maximum dimension in a direction along the main surface larger than a maximum size of the back portion in a direction along the main surface. The base end can be loosely inserted, the engaging portion cannot be inserted, and the depth to the open end of the back is Of the pin standing jigs larger than the axial length of the base end, the large number of pins and the deep portion of the distal end insertion hole are provided with a large number of the pins mounted on the main surface in a random direction or constant. A pin setting step of setting the pin in a state where the distal end of the pin is loosely inserted and the base end is protruded, and a pin setting jig on which the pin is set. A pin insertion step of aligning the substrate body, inserting the base ends of the pins projecting from the pin stand jig into the pin connection holes of the substrate body, and engaging the engaging portions, respectively. A method for manufacturing a pin-erected substrate, comprising:

According to the present invention, in the pin setting step,
Pins of a predetermined shape having a distal end portion and a proximal end portion having different lengths are set on the pin standing jig. If the pin is correctly inserted in the forward direction by moving the pin on the pin stand, the tip of the pin will be inserted beyond the large diameter part to the back. The pin can be made to stand in a state of protruding from the main surface without being tilted too much with respect to the axis of. On the other hand, if the pin is accidentally inserted in the opposite direction, the depth of the large diameter portion is deeper than the length of the proximal end, so that the proximal end is inserted beyond the large diameter portion to the back. It will not be done. Further, in the large-diameter portion, the maximum dimension in the direction along the main surface is larger than that in the back portion, so that even if the pin stands with the tip end side protruding from the main surface, it tends to stand in an inclined state. In other words, once inserted into the distal end insertion hole, it is easy to come off thereafter.

Therefore, the pins can be efficiently inserted in the correct direction, and only the pins whose tips are correctly inserted into the tip insertion holes can be left on the pin setting jig. further,
Repeating the placement of the pin, the movement of the pin, and the removal of the pin a plurality of times in this order makes it possible to more efficiently and easily insert the tips correctly into all of the tip insertion holes and make the pins stand. Here, as a method of moving the pin placed on the pin setting jig in a random direction or a fixed direction, for example, the pin setting jig is vibrated or rocked, or air is applied to the pin. Spraying,
There is a method of directly moving with a brush.

In the pin insertion step, when the pins are inserted into the pin connection holes of the substrate body, all the pins set on the pin setting jig project from the base end side. Only the ends can be inserted into the pin connection holes. As described above, in the present invention, the pins are easily erected on the substrate body with the direction thereof fixed, so that the pins inserted into the pin stand jig in the opposite direction are manually removed as in the related art. There is no need to change the orientation and reinsert. Therefore, it is possible to greatly reduce the time and labor, and it is possible to manufacture the pin standing board at a lower cost as compared with the conventional method of manufacturing the pin standing board.

The substrate body may be made of a resin such as an epoxy resin or a resin using an insulating material made of a composite material of these resins and glass fibers, or may be made of alumina, aluminum nitride, mullite or glass. A ceramic material using an insulating material made of a ceramic such as a ceramic may be used. In addition, a wiring layer formed on the surface or inside thereof, an integrated circuit chip, a wiring board on which the integrated circuit chip is mounted, connection pads for connecting chip components, other electronic components, etc., a solder resist layer, etc. Is also included.

Further, in the above-mentioned method of manufacturing a pin standing board, the pin standing jig has a large-diameter portion of the tip end insertion hole elongated in a predetermined direction.
Preferably, the method is a method of manufacturing a pin-standing substrate, comprising a step of setting a pin in a predetermined direction for moving a large number of the pins placed on the main surface in the predetermined direction.

According to the present invention, in the pin stand jig, the large-diameter portions of the distal-end-side insertion holes are each elongated in a predetermined direction. Then, in the pin setting step, the pins on the pin setting jig are moved along the predetermined direction. In particular, the pin inserted into the pin setting jig in the opposite direction is easily inclined in a predetermined direction in which the large-diameter portion is elongated, and thus easily removed in that direction. Therefore, if the pins on the pin stand jig are moved along the predetermined direction, the pins inserted in the opposite direction are more likely to come off. Therefore, it is possible to more efficiently insert the pin in the correct direction, and leave only the pin whose tip portion is correctly inserted into the tip insertion hole on the pin setting jig. Here, as a method of moving the pin in a predetermined direction, for example, the pin setting jig is tilted and rocked so that the slope direction coincides with the predetermined direction, or air is blown along the pin in the predetermined direction. Or a method of directly moving with a brush that moves in a predetermined direction.

Further, in the above-described method for manufacturing a pin-standing substrate, the pin-standing jig has a large-diameter portion of the tip-end insertion hole elongated in a predetermined direction.
A method for manufacturing a pin standing substrate, comprising a pin removing step of removing the pins along the predetermined direction.

According to the present invention, in the pin stand jig, the large-diameter portions of the distal-end-side insertion holes are each elongated in the predetermined direction. The pin setting step includes a pin setting step of setting a pin on the pin setting jig and a pin inserted in the tip end insertion hole in a reverse direction along the predetermined direction. The pin inserted into the pin setting jig in the opposite direction is particularly likely to be inclined in a predetermined direction in which the large-diameter portion is elongated. Therefore, when the pins are swept along the predetermined direction, the pins are more easily pulled out.
Therefore, it is possible to more efficiently insert the pin in the correct direction, and leave only the pin whose tip portion is correctly inserted into the tip insertion hole on the pin setting jig.

Therefore, by repeatedly placing the pins, moving the pins, and removing the pins a plurality of times in order, the tips can be more efficiently and easily inserted correctly into all the tip insertion holes to erect the pins. be able to. Here, as a method of paying the pin in a predetermined direction, a method of blowing air on the pin in a predetermined direction or directly moving the pin with a brush moving in a predetermined direction can be cited.

The pin 11 used in the present embodiment is made of Kovar, and a Ni-Au plating layer (not shown) is formed on the surface thereof for preventing oxidation. The shape includes an engagement portion 12 having a substantially disc shape, and a distal end portion 13 and a base end portion 14 extending from the engagement portion 12 in a reverse manner to each other and having a substantially cylindrical shape.

Next, FIG. 3A shows an overall view and FIG. 3B shows a partially enlarged sectional view of the pin standing board 20 manufactured in this embodiment. This pin standing board 20 is shown in FIG.
As shown in (a), a substrate body 21 having a substantially plate shape having a substantially square shape of 49.3 × 49.3 mm in plan view and having an upper surface 21A and a lower surface 21B is provided on the lower surface 21B side. Many pins 11 are provided upright. The substrate body 21 has a resin insulating layer on both sides of a core substrate (not shown), and further has a wiring layer between the resin insulating layers. More specifically, as shown in a partially enlarged sectional view of the lower surface side in FIG.

A conductor layer 25 made of copper is formed on the inner wall surface 23A of the pin connection hole 23 and the pin connection hole peripheral edge 21BR on the lower surface 21B of the substrate body 21. The conductor layer 25 is electrically connected to the wiring layer 27A and the like.

It has become. Further, as shown in FIG. 3A, a large number of solder bumps 29 made of eutectic solder are formed on the upper surface 21A of the substrate body 21 for mounting an integrated circuit chip (not shown).

On the other hand, the pin 11 has its base end 14 inserted into the pin connection hole 23 of the substrate body 21, the engaging portion 13 engaging with the pin connection hole 23, and the tip end 14 projecting to the lower surface 21 B side. I have. In addition, the pin 11 includes a base end portion 14 and an engagement portion 13.
(Upper part in the figure) are fixed to the conductor layer 25 with a solder material 28, so that they are respectively erected on the substrate body 21.

Next, a method of manufacturing the pin standing substrate 20 will be described with reference to FIGS. First, the pin setting jig 1 is manufactured by perforating a tip insertion hole 2 with a drill in a substantially square plate made of carbon by a known method. In manufacturing the pin standing substrate 20, in a pin setting step, first, as shown in FIG.
A large number of pins 11 are placed on the main surface 1A of the pin setting jig 1. The pin 11 is formed from a Kovar wire having a diameter substantially equal to the diameter of the distal end portion 13 and the proximal end portion 14 by a known press working, and a Ni-Au plating layer is formed on the surface thereof by a known method. (Not shown).

Thereafter, as shown in FIG. 4 (b), the pin setting jig 1 is vibrated or swung so that the main surface 1A is rotated.
The pin 11 is moved above. At the same time, the air in the distal end insertion hole 2 is sucked from the back surface 1B side of the pin stand jig 1 so that the pin 11 is inserted into the distal end insertion hole 2. By doing so, the pin 11 is inserted into a part of the tip end insertion hole 2 of the pin stand jig 1. At this time, the distal end 13 side of the pin 11 may be inserted into the distal end insertion hole 2, or the base end 14 side may be inserted into the distal end insertion hole 2. However, when the base end 14 side of the pin 11 is inserted, even if it is once inserted, the pin 11 is easily inclined due to the vibration or swinging of the pin stand jig 1, and is easily pulled out. Therefore, as a whole, the distal end 13 side of the pin 11 is easily inserted into the distal end insertion hole 2 of the pin stand jig 1.

Next, as shown in FIG. 4C, in the pin removing step of the pin setting step, the pin BR is not inserted into the tip end insertion hole 2 using the brush BR. Pin 11 is eliminated. At the same time, the proximal end 1
The pin 11 whose 4 side is inserted into the distal end insertion hole 2 is easily tilted by the brush BR, is pulled out from the distal end insertion hole 2 and is removed. On the other hand, the pin 11 having the distal end portion 13 inserted into the distal end insertion hole 2 is not pulled out while standing almost vertically even when the brush BR hits. Therefore, only the pin 11 having the tip portion 13 inserted in the forward direction remains on the pin setting jig 1.

Next, a number of pins 11 are placed on the pin setting jig 1 again, and the pins 11 are moved while the pin setting jig 1 is moved.
Is moved, suction is performed, and the pin 11 is inserted into the distal end insertion hole 2. The pin 11 that has not been inserted or the pin 11 that has been inserted in the opposite direction can be removed again with the brush BR. By repeating such a process a plurality of times, the pins 11 are inserted into all of the tip end insertion holes 2 of the pin setting jig 1 as shown in FIG. In this manner, the pin 11 is attached to the pin setting jig 1.
, The pins 11 are inserted only in the forward direction. That is, since each of the pins 11 has its tip 13 inserted into the tip insertion hole 2 of the pin setting jig 1, for example, There is no need to reinsert the pin 11 inserted in the opposite direction, and the efficiency of temporary pinning operation of the pin 11 can be greatly improved.

Next, in the pin insertion step, FIG.
As shown in the figure, the pin stand jig 1 on which the pins 11 are set is aligned with the substrate main body 21, and the base end 14 of the pin 11 projecting from the pin stand jig 1 is inserted into the pin connection hole 23 of the substrate main body 21. Insert Further, the pin connection hole 2
The engaging portions 12 of the pins 11 are respectively engaged with the pins 3. Note that a solder paste (not shown) for soldering the pins 11 to the substrate body 21 is previously applied on the conductor layer 25 (see FIG. 3B) of the lower surface 21B of the substrate body 21.
It is printed by a known method.

Thereafter, the substrate main body 21 and the pin stand jig 1 stacked via the pins 11 are put into a reflow furnace, and reflowed, and the pins 11 and the substrate main body 21 are fixed to each other with a solder material 28. During the reflow, the melted solder paste is applied to the conductor layer 25 of the substrate body 21 and the base end 14 of the pin 11.
The conductor layer 25 is fixed to the base end portion 14 of the pin 11 and a part of the engaging portion 12 (FIG. 3).
(B)). In this manner, the pins 11 are erected on the substrate main body 21, and the pin erected substrate 20 is completed.

In this embodiment, in the pin setting step, the air in the tip insertion hole 2 is sucked from the back surface 1 B side of the pin setting jig 1, and the pin 11 is inserted into the tip insertion hole 2. It is easy to be. However, the pin 11 can be set up on the pin setting jig 1 only by vibrating or swinging the pin setting jig 1 without performing such suction. In addition, instead of or together with the vibration and swinging of the pin setting jig 1, the pin 11 is set on the pin setting jig 1 by blowing air on the pin 11 or directly brushing the pin 11 with a brush. Can be.

In the pin setting step of the present embodiment, in order to set the pins 11 on the pin setting jig 1 more efficiently, the pins 11 which have not been inserted into the tip end insertion holes 2 in the pin removing step are used. I'm paying off. However, even without such a step, the pins 11 can be set up on the pin setting jig 1 only by moving the pins 11 on the pin setting jig 1 by vibration or swinging.

As described above, the pin stand jig 1 of the present embodiment does not allow the pin 11 to be tilted so much that the base end 14 can be inserted when the distal end 13 of the pin 11 is inserted. It can stand in a protruding state. Further, since the distal end portion 13 of the pin 11 inserted in the forward direction is inserted into the deep portion 4 of the distal end portion insertion hole 2, the pin stand jig 1 is moved or the pin 11 on the main surface 1A is moved. Is relatively difficult to remove even if brushes are brushed off. On the other hand, when the base end 14 side of the pin 11 is inserted, the pin 11 is easily tilted by about 30 degrees, and the pin 11 is easily moved by moving the pin setting jig 1 or brushing it off with the brush BR. Exit. Therefore, the pin 11 can be efficiently inserted in the forward direction, and only the pin 11 having the tip portion 13 correctly inserted into the tip portion insertion hole 2 can be set up on the pin setting jig 1. In addition, since the distal end insertion hole 2 of the pin setting jig 1 has a substantially cylindrical shape in both the large diameter portion 3 and the back portion 4, the processing of the pin setting jig 1 is easy.

Further, according to the method of manufacturing the pin standing board 20 of the present embodiment, in the pin setting step, the pin 1 can be easily and correctly inserted into all the tip end insertion holes 2 of the pin setting jig 1.
The pin 11 can be erected by inserting only the tip 13 side of the pin 1. Furthermore, in the pin insertion step, only the base end 13 side of the pin 11 is inserted into the pin connection hole 23 of the board body 21, so that the pin 11 can be easily erected. Therefore, the pin standing board 2 can be manufactured at a lower cost than in the past.
0 can be produced.

Like the distal end insertion hole 32, the large diameter portion 3
When the pin 11 is inserted into the distal end insertion hole 32 in the forward direction, the distal end of the pin 11 13 is smoothly inserted into the deep portion 34 without being caught in the large-diameter portion 33. Therefore, the pin setting jig 3
When erecting the pin 11 at 1, the pin 11 can be erected more efficiently in the forward direction.

Also, as in the first embodiment, the distal end insertion hole 32 of this modified example has a depth (1.2 mm) of the back portion 34.
Is the axial length of the base end 14 of the pin 11 (1.05 m
m). Further, the base end portion 14 of the pin 11 can be loosely inserted into the large diameter portion 33, and the engaging portion 12 cannot be inserted.

And the large-diameter portion 43 positioned on the main surface 41A side.
And a back portion 44 located in the back. Further, an engagement recess 45 is provided on the main surface 41A side (upper side in the figure) of the large diameter portion 43. The engaging recess 45 is provided with the large-diameter portion 4.
3 even larger, 1.0 mm diameter, 0.5 depth
It has a substantially disk-shaped depression of about mm. Further, since the engagement recess 45 is larger than the diameter of the engagement portion 12 of the pin 11, a part of the engagement portion 12 can be inserted when the pin 11 is erected. The large-diameter portion 43 has the same shape as the large-diameter portion 3 of the first embodiment. Also, back 4
4 is the diameter of the inner part 4 of the first embodiment (diameter 0.
48 mm), but its length is slightly shortened.

As in the first embodiment, the diameter of the large-diameter portion 43 of the distal-end insertion hole 42 is larger than the diameter of the deep portion 44. Also, the depth is the same as the base end 1 of the pin 11.
4 is smaller than the axial length of the distal end portion 13. Further, the proximal end 14 of the pin 11
Can be loosely inserted into the large-diameter portion 43, and the engaging portion 12 is
Cannot be inserted into Therefore, the distal end insertion hole 42
Has an engaging recess 45 on the main surface 41A side of the large-diameter portion 43, but has a pin stand jig 41 having the same, and a method of manufacturing the pin standing board 20 using the pin stand jig 41. In this case, the same effect as in the first embodiment can be obtained.

(Modification 3) Next, Modification 3 of Embodiment 1 will be described. In this modification, FIG. 8A is a partially enlarged view of the pin stand jig 51 viewed from the main surface 51A side, and FIG.
As shown in a partially enlarged cross-sectional view near 2, the distal end insertion hole 5
2 is different from the first embodiment.

The tip end insertion hole 52 is inserted into the pin setting jig 5.
1 penetrates between the main surface 51A and the back surface 51B of the main surface 51A.
The large diameter portion 53 located on the A side and the deep portion 5 located behind the large diameter portion 53
And 4. Further, on the back surface 51B side (the lower side in the figure) of the back portion 54, a back surface side concave portion 55 is provided. The back side concave portion 55 has a substantially cylindrical shape having a diameter of 0.6 mm, which is larger than the diameter of the back portion 54 and the same diameter as the large diameter portion 53, and a depth of 1.0 mm. The large-diameter portion 53 has the same shape as the large-diameter portion 3 of the first embodiment. The diameter of the back portion 54 is the same as the diameter (0.48 mm in diameter) of the back portion 4 of the first embodiment, but the length is shortened.

The diameter of the large-diameter portion 53 of the distal-end insertion hole 52 is larger than the diameter of the deep portion 54 as in the first embodiment. Further, the depth is the base end 14 of the pin 11.
, And smaller than the axial length of the tip portion 13. Further, the base end 14 of the pin 11 can be loosely inserted into the large-diameter portion 53, and the engaging portion 12 cannot be inserted into the large-diameter portion 53. Although the length of the back portion 54 is shortened, when the pin 11 is inserted from the front end portion 13 side, the pin 11 is standing in a state substantially perpendicular to the axial direction of the front end insertion hole 52. Can be maintained. Therefore, as in the present modification, the back surface 51B of the pin stand jig 51
The pin insertion jig 51 and the method of manufacturing the pin standing board 20 using the same are similar to those in the first embodiment with respect to the tip insertion hole 52 having the back side concave portion 55 having a diameter larger than the back portion 54 on the side. Effects can be obtained.

(Modification 4) Next, Modification 4 of Embodiment 1 will be described. In this modification, FIG. 9A is a partially enlarged view of the pin stand jig 61 viewed from the main surface 61A side, and FIG.
As shown in a partially enlarged cross-sectional view near 2, the distal end insertion hole 6
2 is different from the first embodiment.

The tip end insertion hole 62 is inserted into the pin setting jig 6.
1 is a bottomed hole opened only on the main surface 61A side,
It is composed of a large-diameter portion 63 located on the 1A side and a deep portion 64 located behind it. The large-diameter portion 63 has the same shape as the large-diameter portion 3 of the first embodiment. On the other hand, back part 6
4 has the same diameter as that of the back part 4 of the first embodiment, but has a shorter length and does not communicate with the back surface 61B side. In addition, as shown in FIG.
In order to be able to suck in air from the B side, this tip portion insertion hole 6
2 on the back surface 61A side, the back portion 64 and the tip 1 of the pin 11
A suction hole 65 smaller than the diameter of No. 3 may be further provided so as to penetrate between the front and back surfaces.

Since the distal end insertion hole 62 has such a shape, as shown in FIGS.
Is inserted into the distal end insertion hole 62 in the forward direction, the entire distal end portion 13 of the pin 11 is not inserted into the distal end insertion hole 62, so that the engagement portion 12 of the pin 11 is It does not engage with the large diameter portion 63 of the insertion hole 62. However, when the pin upright board 20 is manufactured, even if the pins 11 are erected as described above, the pin connection holes 23 of the board main body 21 are inserted into the pin connection holes 23 of the board body 21 in the pin insertion step as in the first embodiment. The end 13 can be inserted and the engaging portion 12 can be engaged.

Also, as in the first embodiment, the distal end insertion hole 62 of this modified example has the large diameter portion 63 having the inner diameter 6.
4 larger than the diameter. The depth of the pin 11 is greater than the axial length of the proximal end 14 and smaller than the axial length of the distal end 13. Further, the proximal end 14 of the pin 11 can be loosely inserted into the large-diameter portion 63, and the engaging portion 12 cannot be inserted. For this reason, when the pin 11 is inserted in the opposite direction, the pin 11 is easily inclined and easily comes off.

Therefore, even when the engaging portion 12 of the pin 11 does not engage with the large-diameter portion 63 of the distal end insertion hole 62 as in the present modification, the pin standing jig 61 and the pin standing In the method of manufacturing the substrate 20, the same effect as in the first embodiment can be obtained. As shown in FIG. 9B, when the tip insertion hole 62 does not penetrate between the upper and lower surfaces, when manufacturing the pin standing substrate 20,
The air inside the distal end insertion hole 62 cannot be sucked.
Therefore, the pin 11 is inserted into the distal end insertion hole 61 only by vibrating and swinging the pin stand jig 61.

(Embodiment 2) Next, Embodiment 2 will be described with reference to FIGS. FIG. 11A shows the main surface 7 of the pin stand jig 71 of the present embodiment.
A plan view as viewed from the 1A side, FIG. 11 (b) is a partially enlarged view thereof, and FIG. 11 (c) is a partially enlarged cross-sectional view in the vicinity of the tip end insertion hole 72 taken along a dashed line in FIG. 11 (b). In this pin stand jig 71, the large-diameter portion 73 of the distal end insertion hole 72 is
Each of them differs from the first embodiment in that it has a shape that is long in a predetermined direction (horizontal direction in the drawing) among the directions along the main surface 71A. Therefore, the description of the same parts as those in the first embodiment will be omitted or simplified.

The pin setting jig 71 of the present embodiment is made of carbon and has a substantially plate shape having a substantially square main surface 71A and a back surface 71B, similarly to the pin setting jig 1 of the first embodiment. A large number of distal end insertion holes 72 penetrating between the main surface 71A and the back surface 71B are formed in a substantially lattice-like manner, and have a substantially square shape in plan view. As shown in FIG. 11 (c), the distal end insertion hole 72 has a main surface 71A.
A large-diameter portion 73 located on the side and a deep portion 74 located at the back of the large-diameter portion 73 and having the same shape as the deep portion 7 of the first embodiment. Among them, the large-diameter portion 73 has a major diameter of 1.3 mm in plan view,
It has a substantially elliptical shape with a short diameter of 0.6 mm. And FIG.
As shown in (a) and (b), the direction in which the large-diameter portion 73 is elongated is the same as that of the large-diameter portion 73.
Predetermined direction (left-right direction in the figure) along one side (upper side in the figure)
Matches.

Since the large-diameter portions 73 are long in the predetermined directions, as shown in FIG. 11B, of the adjacent tip insertion holes 72, the adjacent tip insertion holes 72 in this direction are removed. In this case, the distance between the large-diameter portions 73 is large. Therefore, when manufacturing the pin stand jig 71, it is easy to form the tip end insertion hole 72, particularly the large diameter part 73, in the pin stand jig 71.

The pins 11 used in this embodiment are the same as those in the first embodiment. That is, the base end portion 14 of the pin 11 can be loosely inserted into the large-diameter portion 73 of the distal end insertion hole 72 of the pin stand jig 71, and the engaging portion 12 of the pin 11 cannot be inserted.
The depth (1.2 mm) of the large-diameter portion 73 corresponds to the base end 13.
Is larger than the axial length (1.05 mm), and shorter than the axial length (3.08 mm) of the distal end portion 14.

Next, FIG. 12 shows a state in which the pin 11 is inserted into the pin stand jig 71. As shown in FIG. 12A, when the pin 11 is inserted in the forward direction,
When the distal end 13 side of the pin 1 is inserted into the distal end insertion hole 72 of the pin stand jig 71, the distal end 13 is moved into the distal end insertion hole 7.
2 is loosely inserted into the large diameter portion 73 and the deep portion 74, and the engaging portion 12 engages with the large diameter portion 73. When the pin 11 is set in this state, even if an external force is applied in a direction parallel to the main surface 71A (horizontal direction in the drawing), the pin 1
1 is hardly inclined and maintains a state of being set substantially perpendicular to the pin setting jig 1.

On the other hand, as shown in FIG.
When the pin 11 is inserted in the opposite direction, that is, the base end 14 side of the pin 11 is
2, the base end 13 is inserted only into the large-diameter portion 73 of the distal-end insertion hole 72, and the engaging portion 12 engages with the large-diameter portion 73. Since the pin 11 in this state is in a state where the base end portion 14 is loosely inserted into the large-diameter portion 73 similarly to the first embodiment, an external force is applied in a direction parallel to the main surface 71A (lateral direction in the drawing). When the pin 11 is added, the pin 11 is easily tilted, so that the pin 11 is easily pulled out of the distal end portion insertion hole 72. In particular, in the pin setting jig 71, the large-diameter portion 73 is elongated in a predetermined direction (left-right direction in the figure), so that when an external force is applied in that direction, as shown by a broken line in the figure, The inserted pin 11 comes off with a large inclination in that direction.

Next, the pin standing board manufactured in this embodiment and the manufacturing method thereof will be described. Pin standing board 20
Is the same as in the first embodiment. As for the manufacturing method, first, similarly to the first embodiment, the distal end insertion hole 72 is drilled in a substantially square plate made of carbon by a known method, and the pin setting jig 7 is formed.
1 is prepared. Next, in the pin setting step, a large number of pins 11 are placed on the main surface 71A of the pin setting jig 71 (see FIG. 4A).

Thereafter, as shown in FIG. 13, the pin setting jig 71 on which the pins 11 are mounted is swung while tilting in a direction along a predetermined direction in which the large-diameter portion 73 is elongated. At the same time, the air in the distal end insertion hole 72 is sucked, and the pin 11 is inserted into the distal end insertion hole 72. At this time, in the distal end insertion hole 72, as in the first embodiment,
The pin 11 may be inserted in a forward direction or a reverse direction. However, in the present embodiment, the large-diameter portion 73 of the distal end insertion hole 72 is long in a predetermined direction, and moreover,
Since the pin setting jig 71 is swung in that direction, the pin 11 inserted in the opposite direction is more easily tilted and easily pulled out. Therefore, as a result, many pins 11 are inserted in the forward direction at this stage.

Next, in the pin removing step of the pin setting step, similarly to the first embodiment, the brush BR
The pins 11 remaining on the pin setting jig 71 are removed, and the pins 11 inserted into the distal end insertion holes 72 in the opposite direction can also be removed (see FIG. 4C). Here, brush BR
Is moved along a predetermined direction in which the large diameter portion 73 of the distal end insertion hole 72 is elongated. In this case, since the large-diameter portion 73 is long in the predetermined direction, the pin 11 inserted in the opposite direction is easily inclined greatly and easily comes off. Therefore, in the present embodiment, in the pin setting step, the large-diameter portion 73 is swung in the elongated predetermined direction and the brush BR is moved in this direction, so that the brush BR can be more efficiently inserted in the forward direction. Only the pin 11 can be left on the pin setting jig 71.

Next, as in the first embodiment, the pins 11
The mounting of the pin 11, the movement of the pin 11, and the removal of the pin 11 are sequentially repeated a plurality of times, and the pins 11 are inserted into all the tip end insertion holes 72 of the pin setting jig 71 (see FIG. 5A). In the present embodiment, the pin 11 erroneously inserted in the opposite direction is easily removed from the distal end insertion hole 72 as compared with the first embodiment, so that the pin 11 can be more efficiently and securely pinned. It can stand on the tool 71. Thereafter, in the same manner as in the first embodiment, in the pin insertion step, the base end 14 of the pin 11 is inserted into the pin connection hole 23 of the board main body 21, and the engaging portions 12 are respectively engaged (FIG. b)). Then, the pins 11 are fixed to the board body 21 by soldering, and the pins 11 are erected on the board body 21.

As described above, when the pin 11 is inserted in the forward direction, the pin setting jig 71 of the present embodiment also sets the pin 11 upright with the base end 14 protruding substantially vertically. Can be Further, since the distal end portion 13 is inserted into the deep portion 74 of the distal end portion insertion hole 72, even if an external force is applied such as moving the pin setting jig 71, it is relatively difficult to come off. On the other hand, when the pin 11 is inserted in the opposite direction, the large-diameter portion 73 is easily inclined particularly in the direction in which the pin 11 is lengthened, and is easily released by an external force. Therefore, the pin 11 can be efficiently inserted in the forward direction, and only the pin 11 inserted in the forward direction can be set up on the pin setting jig 71.

Further, according to the manufacturing method of the pin standing board 20 of the present embodiment, in the pin setting step, all the front end insertion holes 72 of the pin setting jig 71 can be easily and correctly inserted. By inserting only the side, the pin 11 can be set up. In particular, since the large-diameter portion 73 of the distal end insertion hole 72 is elongated in a predetermined direction, and furthermore, the pin setting jig 71 is swung along the predetermined direction. It is easy to fall out of the distal end insertion hole 72. In addition, since the pin 11 is moved along the predetermined direction by the brush BR, the pin 11 erected in the opposite direction is easily pulled out from the distal end portion insertion hole 72 and removed. Furthermore, in the pin insertion step, only the base end 13 side of the pin 11 is inserted into the pin connection hole 23 of the board body 21, so that the pin 11 can be easily erected. Therefore, the pin standing substrate 20 can be manufactured at lower cost than in the past.

(Modification 1) Next, Modification 1 of Embodiment 2 will be described. Pin Standing Jig 81 of the Modification
14A, the main surface 81 of the pin setting jig 81 is shown in FIG.
A plan view as viewed from the A side, FIG. 14 (b) is a partially enlarged view thereof, and FIG. 14 (c) is a partially enlarged cross-sectional view of the vicinity of the tip end insertion hole 82 in the one-dot chain line in FIG. 14 (b). In this modification, the shape of the distal end insertion hole 82 is different from that of the second embodiment.

The distal end insertion hole 82 is
1 penetrates between the main surface 81A and the back surface 81B of the main surface 81A.
It is composed of a large common diameter portion 83 located on the A side and a plurality of deep portions 84 (two in this example) located behind the large diameter portion 83. The large-diameter common portion 83 has a substantially oval shape in a plan view, with the large-diameter portions connected to each other at two adjacent tip end insertion holes 82. As shown in FIG. 14A, the common large-diameter portion 83 has two large-diameter portions adjacent to each other in a predetermined direction (left-right direction in the drawing) along one side (upper side in the drawing) of the pin setting jig. And are elongated in this predetermined direction. The inner part 84 of the distal end insertion hole 82 has the same shape as that of the second embodiment.

In the distal end insertion hole 82, as in the second embodiment, the large-diameter portion 83 has a longer diameter and a shorter diameter than the diameter of the deep portion 84. The depth of the pin 11 is greater than the axial length of the proximal end 14 and smaller than the axial length of the distal end 13. In addition, pin 1
The one base end portion 14 can be loosely inserted into the large common diameter portion 83, and the engaging portion 12 cannot be inserted. Therefore, in the pin stand jig 81 of the present modification and the method of manufacturing the pin stand board 20 using the same, the same effects as in the second embodiment can be obtained.

Further, in this modification, since the adjacent large diameter portions are connected to form the common large diameter portion 83, when the pin 11 is inserted in the opposite direction, particularly, the pin 11
The large common diameter portion 83 is extremely inclined in the elongated predetermined direction, and easily comes off. For this reason, the pin 11 can be set up on the pin setting jig 81 more efficiently and correctly. Also,
Since the large-diameter portions are the common large-diameter portions 83 connected to each other, the pin stand jig 81 can be easily manufactured.

(Modification 2) Next, Modification 2 of Embodiment 2 will be described. Pin Standing Jig 91 of this Modification
15 (a) is a plan view as viewed from the main surface 91A side, FIG. 15 (b) is a partially enlarged view thereof, and FIG. 15 (c) is a tip end insertion hole at a dashed line in FIG. 15 (b). A partial enlarged cross-sectional view near 92 is shown. In the present modification, the shape of the tip end insertion hole 92 of the pin stand jig 91 is different from that of the second embodiment.

The tip end insertion hole 92 is also fixed to the pin stand jig 9.
1 penetrates between the main surface 91A and the back surface 91B.
It comprises a large common diameter portion 93 located on the A side and a deep portion 94 located behind the large diameter portion 93. Among them, the large common diameter portion 93 is shown in FIG.
As shown in (a), the large-diameter portions are connected to each other in all of a plurality of tip end insertion holes 92 adjacent in a predetermined direction (left-right direction in the figure) along one side (upper side in the figure) of the pin stand jig 91. are doing. That is, the large common diameter portion 93 is
The first main surface 91A is formed in a groove shape from the edge to the edge. Each of the large common diameter portions 93 is formed to be long in a predetermined direction (the left-right direction in the drawing). In addition, the back part 94 of the front end part insertion hole 92 has the same shape as that of the second embodiment.

In the distal end insertion hole 92, the size in the left-right direction and the vertical direction of the large-diameter common portion 93 is larger than the diameter of the back portion 94, as in the second embodiment. The depth of the pin 11 is greater than the axial length of the proximal end 14 and smaller than the axial length of the distal end 13. Further, the base end portion 14 of the pin 11 can be loosely inserted into the large common diameter portion 93, and the engaging portion 12 cannot be inserted. Therefore, the pin stand jig 91 of the present modification and the pin stand board 20 using the same
In the manufacturing method of the second embodiment, the same effect as in the second embodiment can be obtained. Further, in the present modification, since the plurality of large-diameter portions are connected to form the common large-diameter portion 93, the pin 11 inserted in the opposite direction is extremely easy to come off similarly to the first modification. Therefore, the pin 11 can be efficiently and correctly set on the pin setting jig 91.

In the above, the present invention has been described with reference to the respective embodiments.
