[Industrial applications]

When testing or measuring an electronic component having a large number of terminals, such as an IC, the present invention mounts the component on a component receiver of a test device, and furthermore, each terminal of the component and each terminal of the receiver. The present invention relates to a method of aligning a contact so as to surely contact the contact.

[Conventional technology]

FIG. 6 is a view showing a multi-terminal component, (a) is a plan view,
(B) is a side view. Reference numeral 1 denotes a multi-terminal component such as an IC, and many terminals 1a and 1b protrude from both ends of a package 1p made of synthetic resin or the like.

7 and 8 are partial sectional side views showing an apparatus used for a conventional method for positioning a multi-terminal component. Reference numeral 2 denotes a receiving member for the component 1, and a terminal 3 is provided in a body 3 made of an insulator.
Contacts 4a, 4b are provided corresponding to 1a, 1b, and test terminals 5a, 5b integral with the respective contacts 4a, 4b are connected to a tester 6.

A package receiver 7 is provided between the contacts 4a and 4b via a compression coil spring S1.

An opening / closing lid 9 is attached to one end of the main body 3 via a support shaft 8, and terminal holding claws 10 a and 10 b are provided on the inner surface of the opening / closing lid 9.

To test and measure parts with this device,
The component 1 is placed on the package receiver 7 of the receiver 2, and the component terminals 1a, 1b are aligned with the contacts 4a, 4b of the receiver. Since the component 1 such as an IC has a large number of terminals in a direction perpendicular to the paper surface, it is necessary to perform high-precision alignment so that all these terminals exactly overlap the corresponding receiver-side contacts.

After the alignment, as shown in FIG. 8, when the cover 9 is closed, the holding claws 10a and 10b overlap the terminals 1a and 1b of the components on the package receiver 7 directly and receive the respective component terminals 1a and 1b. The contacts 4a and 4b on the tool side make reliable contact. In this state, after performing tests and measurements, the opening / closing lid 9 is opened, the component 1 is taken out from the receiver 2 side, the next component is attached in the same manner, and the same operation is repeated.

[Problems to be solved by the invention]

As described above, it is necessary to place the component 1 on the package receiver 7 and to align the component terminals 1a, 1b with the contacts 4a, 4b.
Removal is done manually. Therefore, the work required skill and the efficiency was poor.

Therefore, in order to improve the workability, a component guide 11 as shown in FIG. The component guide 11 has four positioning walls 11a in which the corners 1c of the package 1p enter, and a guide inclination 11b is formed above each positioning wall 11a.

When the multi-terminal component 1 shown in FIG. 6 is inserted from above the component guide 11, the corner 1c of the package 1p becomes the inclined portion 11b.
The terminals 1a and 1b are positioned in the openings 12a and 12b between the positioning walls 11a and 11a. In this state, the component terminals 1a and 1b are aligned on the contacts 4a and 4b of the receiving member 2.

However, in recent years, with the advent of high-density components, the component terminals 1a and 1b have become thinner, the pitch between the terminals has become narrower, and the package has also become smaller. As a result, it is more difficult to position the component terminals.

That is, in the corner 1c of the package 1p, only the region A where no terminal exists between the side wall and the terminals 1a and 1b is X
Cannot be used for positioning in the direction. In the positioning wall 11a of the component guide 11, the guide area B that can be used for positioning is smaller, and A> B.

As is well known, in a high-density component, the guide region A
Since there is a tendency of miniaturization, the guide area B of the component guide 11 also has a minute dimension, and even if the component guide 11 is provided,
The operation of inserting the component into the component guide 11 is troublesome, and there is also a problem that the terminals 1a and 1b hit the component guide 11 and are damaged.

The technical problem of the present invention is to pay attention to such a problem, and to automatically and surely position the component terminals on the respective contacts of the component receiver even in a multi-terminal component having a high terminal density. It is to make.

[Means for solving the problem]

Next, a practical example of how the multi-terminal component positioning method according to the present invention is embodied will be described with reference to examples. FIG. 1 is a side view for explaining the basic principle of the present invention.

According to the method of the present invention, tests and measurements are performed in a state where the terminals 1a and 1b of the multi-terminal component are aligned with and brought into contact with the contacts 4a and 4b of the receiving device. A supported lid 9 is provided, and the lid has means for positioning the multi-terminal component 1.

In this device, first with the lid 9 opened,
With the multi-terminal component 1 attached to the lid 9 and positioned,
The lid 9 is held.

Next, by closing the lid 9 and placing it on the receiver 2, each terminal 1a, 1b of the multi-terminal component 1 is contacted with each contact 4a, 4b of the receiver 2.
Contact.

[Action]

As in the prior art, on the receiving tool 2, aligning the terminals 1a and 1b of the multi-terminal component with the contacts 4a and 4b,
Difficult as described above. On the other hand, according to the present invention, the multi-terminal component 1 is attached to the lid 9 that is positioned in advance with respect to the holder 2, and the terminals 1a and 1b are aligned on the lid 9. In this state, the multi-terminal component 1 is held by the lid 9,
When the multi-terminal part 1 is turned upside down when it is rotated on the receiving member 2 and placed on the receiving member 2, the terminals 1a and 1b are aligned just above the contacts 4a and 4b. Overlap.

The lid 9 does not have the contacts 4a and 4b and has a simple structure, so that even a high-density multi-terminal component can be accurately positioned.

〔Example〕

Next, a practical example of how the multi-terminal component positioning method according to the present invention is embodied will be described with reference to examples. 2 to 4 are partial cross-sectional side views showing an apparatus used for the method for positioning a multi-terminal component according to the present invention. In this device, a package receiver 7 is mounted on a main body 3 via a compression coil spring S1 on a side of a receiver 2. Therefore, as shown in FIG. 3, when the cover 9 which is attached to the main body 3 of the receiving member 2 via the support shaft 8 so as to be openable and closable is closed,
Are placed on the package receiver 7, and the component terminals 1a, 1b
The package receiver 7 is pressed down against the compression coil spring S1 until the contacts 4a, 4b are surely brought into contact with the contacts 4a, 4b, whereby the contacts between the terminals 1a, 1b and the contacts 4a, 4b are ensured.

The package receiver 17 is also mounted inside the lid 9 via a compression coil spring S2. Then, a vacuum suction plate 16 is attached to the package receiver 17. In addition, as shown in FIG.
A rod 19 penetrating the compression coil spring S2 is supported by the lid 9.

A guide slope 15 is provided on the opening side of the positioning recess 14.
Are formed. Therefore, even when the terminals 1a and 1b are not aligned just above the positioning recess 14, the terminals
The leading ends of 1a and 1b can be guided by the guide slope 15 so as to enter the positioning recess 14. For this reason, it is possible to mechanize the multi-terminal component without requiring any manpower to position the multi-terminal component on the lid 9 side.

Now, as shown in FIG.
When the vacuum suction device is operated with the terminals 1a and 1b inserted into the package 14 and the package 1p placed on the package receiver 17, the package 1p is suction-held by the vacuum suction plate 16.

In the state where the component 1 is vacuum-sucked on the lid 9 side,
When the lid 9 is closed, the state shown in FIG. 3 is obtained. That is, the terminal
1a and 1b are sandwiched between the lid 9 and the contacts 4a and 4b,
The contact between the terminals 1a and 1b and the contacts 4a and 4b is ensured. At this time, after the terminals 1a and 1b abut against the contacts 4a and 4b, the component 1
Is retracted toward the lid 9 against the compression coil spring S2, so that the pressing force of the lid 9 can be reliably transmitted to the terminals 1a and 1b.

A hook 21 is attached to the tip of the lid 9 via a support shaft 20. When the lid 9 is closed, the hook 21 is hooked on the receiver 2 side, and presses the terminals 1a, 1b against the contacts 4a, 4b. Locked in the locked state.

After performing tests and measurements in this state, the hook 9 is removed and the lid 9 is opened while the vacuum suction device is operated, and the lid 9 is inverted as shown in FIG. The state is such that the component 1 is placed on 17. here,
After releasing the vacuum suction and making the part 1 free, the part 1 is taken out by an automatic machine and the next part is received in a package.
Comes on 17

〔The invention's effect〕

As described above, according to the present invention, the component positioning means and the holding means are provided inside the lid 9 attached via the support shaft to the component receiving member 2 side, and the component 1 is inserted into the lid 9 side. Is positioned and held at a predetermined position on the lid 9. Next, while holding the component 1, the cover 9 is closed and put on the receiver 2, and the terminals 1 a, 1 b of the component 1 are brought into contact with the contacts 4 a,
Pressed on 4b to make electrical connection with the tester side.

As described above, the contacts 4a, 4b, etc. exist for positioning the terminals 1a, 1b of the component 1 on the side of the lid 9 on which the positioning portion 13 is formed in a fixed relationship with the contacts 4a, 4b of the receiver 2. Unlike the case where the positioning is directly performed on the receiver 2 having a complicated structure, the positioning on the cover 9 enables accurate positioning even for a thin terminal and a small external component, and also improves workability. It is excellent. In addition, since the terminals 1a and 1b of the component 1 are brought into contact with the contacts 1a and 1b of the holder 2 in the positioned state, the terminals 1a and 1b can be prevented from being deformed. Further, since the position where the component 1 is mounted and the position where the component 1 is taken out are the same, automation becomes easy.
