In order to avoid such soldering defects, inspection of the substrate on which the solder is printed by the screen printer (printing inspection) and inspection of the screen mask that is indispensable for printing the solder (mask inspection) are important. . For this reason, in recent years, a board mounting line including a screen printing machine on which an inspection process is mounted and a printing inspection apparatus independent of the printing apparatus has been proposed (for example, see Patent Document 1).

A pattern or a screen mask is imaged, and the solder or mask opening corresponding to the inspection point in the imaged data is subjected to image processing, or acquired by data conversion from data used for creating the mask. Subsequently, the user repeats the actual inspection and correction on the condition data such as the illumination setting when imaging the inspection point in the print inspection, various threshold values related to the image processing, and the allowable value used for the determination. Set manually.
Similarly, in the case of mask inspection, an inspection point is set on the screen mask, and basic data of all of the inspection points, for example, data on the opening position and the opening size of the mask, is applied to the screen mask to be executed prior to the mask inspection. Acquired by image processing based on imaging data or data conversion from data used to create a mask. Subsequently, condition data such as illumination settings when imaging the inspection point, various threshold values related to image processing, and allowable values used for determination are manually input while repeating actual inspection and correction.

When the substrate 10 is fixed on the stage 25, the screen printing machine 2 drives the first Y-axis motor 26 to move the stage 25 in the positive direction in the Y direction, and also drives the X-axis motor 28 as necessary. As a result, the stage 25 is arranged at a predetermined position below the substrate recognition camera 50, for example, at a position where the entire substrate 10 is included in the imaging range of the substrate recognition camera 50. Subsequently, the board 10 is imaged by the board recognition camera 50, the position of the positioning mark provided on the board 10 is recognized from the recognition data based on this imaging data, and a position serving as a reference for fixing the board 10 on the stage 25 A deviation (substrate fixation deviation) from the position where the substrate 10 is actually fixed on the stage 25 is detected (step S402).

The cream solder is filled in the printing holes 31 of the screen mask 30 by reciprocating in the Y direction (in this embodiment) (step S405).

Specifically, for example, the screen printing machine 2 drives the second Y-axis motor 46 and the second Z-axis motor 47 to move the first squeegee head 43 to a predetermined position on the screen mask 30, as shown in FIG. A squeegee at the lower end is brought into contact with the vicinity of the end portion on the negative direction side in the Y direction of 30 so that the side of the end portion is parallel to the longitudinal direction of the first squeegee head 43. At this time, the second squeegee head 44 is positioned above.
Subsequently, the screen printing machine 2 supplies cream solder between the position where the first squeegee head 43 abuts on the screen mask 30 and the position where the printing holes 31 are provided. When the cream solder is supplied, the screen printing machine 2 drives the second Y-axis motor 46 to bring the squeegee at the lower end of the first squeegee head 43 into contact with the screen mask 30 in the Y direction of FIG. Move in the positive direction. Thereby, the cream solder supplied onto the screen mask 30 is moved in the positive direction in the Y direction on the screen mask 30 by the first squeegee head 43, thereby filling the printing holes 31. At this time, since the second squeegee head 44 is positioned above, it does not contact the cream solder.

When the first squeegee head 43 passes through all the printing holes 31 provided in the screen mask 30, the second Y-axis motor 46 is stopped and the screen printing machine 2 drives the third Z-axis motor 48 to 2 The squeegee head 44 is lowered, and the edge of the second squeegee head 44 and the side of the second squeegee head 44 are placed at a predetermined position on the screen mask 30 near the end of the screen mask 30 shown in FIG. The longitudinal direction is made parallel and the squeegee at the lower end is brought into contact. At this time, the screen printing machine 2 drives the second Z-axis motor 47 to move the first squeegee head 43 to the upper position.
Subsequently, the screen printing machine 2 drives the second Y-axis motor 46 to move in the negative direction in the Y direction of FIG. 2 with the squeegee at the lower end of the second squeegee head 44 in contact with the screen mask 30. Let Thus, the cream solder moved by the first squeegee head 43 is filled in the printing holes 31 by being moved in the negative direction in the Y direction on the screen mask 30 by the second squeegee head 44. At this time, since the first squeegee head 43 is positioned above, it does not contact the cream solder.

  After the cream solder is filled and pressed in the printing holes 31 of the screen mask 30 and printed in this way, the screen printing machine 2 drives the first Z-axis motor 27 to lower the stage 25 in the negative direction in the Z direction. Then, the substrate 10 and the screen mask 30 are separated from each other (step S406), and printing is completed.

[Inspection]
When printing is completed, the screen printing machine 2 drives the first Y-axis motor 26 to move the stage 25 in the positive direction in the Y direction, and if necessary, the first Z-axis motor 27, the X-axis motor 28, and By driving at least one of the θ-axis motors 29, the stage 25 is moved to a predetermined position below the print inspection camera 60, for example, a position where the entire substrate 10 is included in the imaging range of the print inspection camera 60. An inspection is performed (step S407). The screen printer 2 according to the present embodiment is characterized by a method for creating inspection data and point data used for the print inspection.

First, as shown in FIG. 5, the screen printing machine 2 images the substrate 10 on which the cream solder is printed by the print inspection camera 60. Various settings such as illumination at the time of imaging are made based on condition data.
As shown in FIG. 6, for example, visual fields 11 a to 11 f are assigned to the imaging data for each device and inspection point mounted on the substrate 10. Based on the imaging data and the condition data for inspecting the substrate 10 stored in advance in the library 72a of the storage unit 72, the image processing unit 73 determines the size of the printing solder and the planar shape state of each inspection point. Create recognition data including.
Here, the inspection point can be freely set as appropriate, such as a solder unit or a device unit.

  The inspection determination unit 75 extracts the size and planar shape of the solder printed on the inspection point from the recognition data. Further, basic data is extracted from inspection data or point data used for printing inspection of the substrate 10 stored in advance in the storage unit 72. Then, for each inspection point, the size and shape of the solder extracted from the recognition data and the information on the size and shape of the solder to be printed on the inspection point based on the basic data are compared or pattern-matched, and the result is It is determined whether printing has been performed normally by comparing with the condition data associated with the inspection point.

[Board unloading]
When no printing failure is found by the above-described print inspection, that is, when printing is performed normally (step S408: NO), the screen printing machine 2 includes the first Y-axis motor 26 and, if necessary, the first Z-axis motor 27, X The shaft motor 28 and the θ-axis motor 29 are driven to move the stage 25 to a predetermined position and, for example, are carried out to the mounter 3 provided on the negative direction side in the X direction in FIG. The unloaded substrate 10 is subjected to processes following the mounters 3 and 4 and the reflow furnace 5, that is, mounting and firing of devices.
On the other hand, when a printing failure is found by the print inspection (step S408: YES), the screen printing machine 2 carries out the substrate 10 in which the printing failure is found to the outside of the screen printing machine 2 (step S410). An instruction to request removal is displayed on the display device 83 (step S411). Here, the screen printer 2 may be provided with a container that collects only the substrates on which printing defects are found. In this case, when a printing failure is found, the screen printing machine 2 automatically carries the substrate on which the printing failure is found to the container. As a result, it is possible to save the trouble of an operator who removes a substrate in which a printing defect is found, which is very convenient.

Next, with reference to FIG. 7, each operation | movement with the mask test | inspection of the screen printer 2 concerning this Embodiment is demonstrated. FIG. 7 is a flowchart showing each operation involving the mask inspection of the screen printer 2 according to the present embodiment.
In FIG. 7, steps S701 to S706 showing the steps of substrate loading, positioning, printing, and substrate unloading are the same as the print inspection described with reference to FIG.

[Inspection]
When the substrate 10 on which the solder is printed is carried out to the next process (step S707), the screen printing machine 2 performs a mask inspection (step S708).

The screen printing machine 2 drives the first Y-axis motor 26 to move the stage 25 in the positive direction in the Y direction and, if necessary, the first Z-axis motor 27, the X-axis motor 28, and the θ-axis motor 29. By driving at least one of them, the stage 25 is moved to a predetermined position below the screen mask 30, for example, to a position where the entire substrate 10 is included in the imaging range of the mask recognition camera 80. The mask 30 is imaged. Various settings such as the illumination setting at the time of imaging are made based on the condition data.
Based on the image data taken by the mask recognition camera 80 and the condition data for inspecting the screen mask 30, the image processing unit 73 uses the same method as that for the substrate 10 described with reference to FIG. Create The inspection determination unit 75 extracts the state of the screen mask 30 at the inspection point, particularly the size and shape of the printing hole 31. Further, basic data is extracted from inspection data or point data used for mask inspection of the screen mask 30 stored in advance in the storage unit 72. For each inspection point, the inspection determination unit 75 compares and compares the shape and size of the printing hole 31 of the screen mask 30 extracted from the recognition data and information on the shape and size of the printing hole 31 of the inspection point based on the basic data. By matching and comparing the result with condition data associated with the basic data, it is determined whether or not the state of the screen mask 30 is normal. This determination is made when, for example, foreign matter or solder clogging in the opening of the screen mask 30, flux on the back of the screen mask 30, solder bleeding, or the like is detected, the inspection determination unit 75 determines that the state of the screen mask 30 is abnormal. Judge that there is.

[Mask cleaning]
If an abnormality of the screen mask 30 is found by the mask inspection described above (step S709: YES), the screen printing machine 2 displays an instruction to clean the screen mask 30 on the display device 83 (step S710). Here, the screen printer 2 may be provided with a mechanism for automatically cleaning the screen mask 30. In this case, the screen printer 2 may automatically clean the screen mask 30 when a mask abnormality is found. As a result, the operator's trouble of cleaning the screen mask 30 can be saved, which is very convenient.
If no abnormality of the screen mask 30 is found by the mask inspection (step S709: YES), the screen printing machine 2 returns to step S701 to print the next substrate 10.

Next, a method of creating inspection data or point data used for the print inspection or mask inspection as described above will be described with reference to FIG. FIG. 8 is a flowchart showing an operation of creating inspection data or point data of the screen printer 2 according to the present embodiment.
Here, it is assumed that at least one inspection data or point data previously created is registered in the library 72a stored in the storage unit 72. In the following description, it is assumed that registration is performed in the library 72a in units of point data, but registration in units of inspection data is also possible.

[Get basic data]
When creating inspection data for print inspection or mask inspection, the user first sets inspection points on the substrate 10 or the screen mask 30, and creates basic data regarding the position and shape of the inspection points (step S801). This basic data is obtained by data conversion from the data used when the screen mask 30 is created, a solder pattern on the substrate 10 that is a reference on which the solder is actually printed is photographed, and this photographed image is imaged. It can be obtained by a method of processing and detecting, a method of photographing the printing hole 31 of the screen mask 30, and detecting and obtaining this photographed image.

[Inspection field assignment]
Next, in order to collectively inspect and inspect a plurality of inspection points with the same imaging data, as shown in FIG. 6, an inspection visual field is assigned for each inspection point (step S802).

[Shared settings]
Here, the sharing determination unit 78 determines whether or not sharable point data is registered in the library 72a for the input inspection point (step S803). Specifically, the sharing determination unit 78 compares the input basic data of the inspection point with the basic data of the point data registered in the library 72a.
Note that the order in which the input basic data is compared with the basic data of any point data among the basic data of the plurality of point data registered in the library 72a can be set as appropriate.

When sharable point data exists in the library 72a (step S803: YES), the sharing determination unit 78 sets the point data of the inspection point input based on the point data (step S811). Specifically, when the point data having basic data similar to the basic data of the input inspection point is registered in the library 72a, the sharing determination unit 78 determines that the condition is associated with the similar basic data. Data is set as condition data for the input inspection point. As a result, the condition data of the input inspection point is automatically generated.
Here, the similarity of the basic data means that when the size or shape of the solder to be printed or the size or shape of the printing hole 31 of the screen mask is compared, the value is within a predetermined range or the same. In this case, the sharing determination unit 78 determines that the basic data is similar. The predetermined range or the like is stored in the storage unit 72, and can be freely set as appropriate.

  Note that this similarity is based on the solder shape and size extracted from the recognition data or the information on the shape and 31 of the printing hole 31, and the solder shape and size extracted from the basic data or the information on the shape and 31 of the printing hole 31. Alternatively, the determination may be made by expressing each vector and taking the inner product. Here, the vector expression can be set freely as appropriate, and the setting condition can be included in the condition data.

[Condition data setting]
If no sharable point data exists in the library 72a (step S803: NO), the user sets condition data corresponding to the input inspection point by manual input or the like (step S804).
Such setting of the condition data is performed until the setting of all the inspection points is completed.

[Examination execution condition setting]
When the setting of the condition data for all the inspection points is completed (step S805: YES), the common determination unit 78 determines under what conditions the print inspection or mask inspection of the created inspection data is executed during continuous production. Determination is made (step S806). As this condition, for example, it is performed by thinning or after cleaning of the screen mask 30.

[Inspection trial]
Although the creation of the inspection data is completed by the steps so far, in order to confirm whether or not the inspection data has been correctly created, the inspection data indicates the variation in the printing state when printing is actually performed by the screen printer 2. For the purpose of reflecting the error in the data and correcting it to appropriate data, an inspection trial is performed using the generated inspection data (step S807).
If it is determined by this trial that the inspection data is not correctly created (step S812: NO), the user corrects the inspection data (step S812). The correction of the inspection data may be automatically performed by the common determination unit 78 using a program stored in advance in the storage unit 72 based on the inspection trial result.

[Inspection data registration]
When it is confirmed that the examination data created by this trial has been created correctly (step S808), the examination determination unit 75 selects all point data included in the created examination data or any point of the created examination data. Data is registered in the library 72a stored in the storage unit 72 (step S809).

Thus, by registering the created point data in the library 72a, creation of point data and inspection data becomes easy.
For example, as shown in FIG. 9A, when equivalent inspection points 12a to 12e exist on the substrate 10, any one of the inspection points 12a to 12e is created and registered in the library 72a. . As an example, it is assumed that the point data of the inspection point 12a is registered in the library 72a. Then, according to the present embodiment, as shown in FIG. 9B, the sharing determination unit 78 shares the point data of the inspection point 12a with each of the inspection points 12b to 12e, that is, the point of the inspection point 12a. Condition data included in the data, for example, threshold values, area allowance values, position allowance values, and the like are associated with each basic data of the inspection points 12b to 12e to create point data and register it in the inspection data. Thereby, the point data of the inspection points 12b to 12e among the inspection data of the substrate 10 are automatically created without the user creating each condition data. Therefore, according to this embodiment, it can be said that inspection data and point data can be easily created.
Note that the inspection data for the mask inspection can be easily performed by the same method.

As another example, according to the present embodiment, inspection data and point data are easily created even when inspection points of the same device exist on the substrate 10A and the substrate 10B as shown in FIG. It becomes possible.
In this case, when the inspection data A of the substrate 10A is created, the point data of the inspection point 12f of the device QFP1 is registered in the library 72a. Then, when creating the inspection data B of the substrate 10B, the common determination unit 78 uses the point data of the device QFP1 already registered in the library 72a for the point data of the inspection point 12g of the same device QFP1 as the substrate 10A. The condition data that is shared, that is, included in the point data of the device QFP1, is registered in the inspection data B of the substrate 10B in association with the basic data of the inspection point 12g. Thereby, the point data of the inspection point 12g among the inspection data B of the substrate 10B is automatically created without the user creating condition data. Therefore, according to the present embodiment, it can be said that the point data of the inspection data B and the inspection point 12g can be easily created.
Note that the inspection data for the mask inspection can be easily performed by the same method.

As another example, the point data already registered in the library 72a is grouped according to conditions such as the size and shape of the inspection point, the distance to the adjacent inspection point, and the point data is shared based on this group. This also facilitates the creation of inspection data.
For example, as shown in FIG. 11, when the inspection points are grouped according to the plane size, the inspection points 12h to 12j on the substrate 10C correspond to the point data # 1 to # 3, respectively. The point data # 1 to # 3 registered in the library 72a are shared with the inspection data of the substrate 10C. That is, the condition data included in the point data # 1 to # 3 is registered in the inspection data of the substrate 10C in association with the basic data of the inspection points 12h to 12j. Thereby, the inspection data of the substrate 10C can be easily created only by sharing the point data registered in the library 72a.
Note that the inspection data for the mask inspection can be easily performed by the same method.

Also, the inspection data and point data may be registered in the library 72a every time they are created. In this way, the library 72a is automatically grown and enriched. Then, when new inspection data is created, if the inspection data registered in the library 72a is enriched, the probability that inspection data that can be shared is high is also increased. Therefore, new inspection data or point data can be created only from inspection data or point data already registered in the library 72a. This eliminates the need for the user to create condition data when creating new inspection data or point data, so that the user can easily create inspection data or point data.
Note that the inspection data for the mask inspection can be easily performed by the same method.

  The method for creating inspection data as described above is not limited to the form built in the screen printer 2 as in the present embodiment, but is an apparatus independent of the screen printer, an apparatus for controlling the entire mounting line 1, and the mounter 3. , 4, the reflow furnace 5 and the substrate transfer conveyor 6 can be applied to apparatuses other than the screen printer 2 constituting the mounting line 1.

  Imaging of the substrate 10 serving as a printed reference performed for acquiring basic data in the production of substrate inspection data, and imaging of the screen mask 30 performed for acquiring basic data in creating inspection data of mask inspection Alternatively, it may be performed by the screen printing machine 2 in which the inspection process is mounted, or by an independent print inspection apparatus different from the printing apparatus. In this case, it is possible to mount and fix the reference substrate 10 on the stage 25 and to image the solder pattern on the substrate with the substrate recognition camera 50 or the print inspection camera 60 as in the print inspection after printing. Further, the screen mask 30 is installed in another print inspection apparatus independent of the screen printer 2 and the printing apparatus, and the screen mask 30 is imaged by a mask recognition camera 80 provided in the print inspection apparatus. The imaging data obtained by these is stored in the storage unit 72 of the control device 70 of the screen printing machine 2 or the print inspection apparatus, and steps S801 to S806 and S811 of FIG.

  When the basic data and condition data of the inspection points on the substrate 10 and the screen mask 30 are set by data conversion from data used for creating the mask, the above steps S801 to S806 and S811 are performed by the screen printer 2 It may be implemented not only by an independent print inspection apparatus different from the printing apparatus but also by an information processing apparatus such as an independent computer other than these. In this case, the information processing apparatus has at least the same configuration as the storage unit 72, the library 72a, the image processing unit 73, the display unit 76, the common determination unit 78, and the control unit 79 of the control device 70 described above. Based on the data to be used, basic data and condition data for each inspection point on the substrate 10 and the screen mask 30 are set. Thereby, not only the independent printing inspection apparatus different from the screen printer 2 and the printing apparatus but also the basic data and condition data of the inspection point can be set by an independent information processing apparatus different from these.

  When setting the basic data and condition data of the inspection points of the substrate 10 and the screen mask 30 using the imaging data, not only the print inspection apparatus independent of the screen printing machine 2 and the printing apparatus but also the above-described one. You may make it implement with information processing apparatus. In this case, image data is transmitted to the information processing apparatus via a communication line such as a LAN from a printing inspection apparatus independent of the screen printing machine 2 or the printing apparatus, or independent of the screen printing machine 2 or the printing inspection apparatus. The imaging device captures an image of the standard printed circuit board 10 and the screen mask 30, and transmits this imaging data to the information processing device. Then, the information processing apparatus sets basic data and condition data for each inspection point on the substrate 10 and the screen mask 30 based on the received imaging data. Thereby, even when imaging data is used, not only the independent printing inspection apparatus different from the screen printer 2 and the printing apparatus, but also the basic data of the inspection point by an independent information processing apparatus different from these. And condition data can be set.

  The inspection data obtained by performing steps S801 to S806 and S811 by the information processing apparatus described above is a storage medium such as a phase change optical disk, a magnetic tape, a magneto-optical disk, a magnetic disk, or a flash memory, or a communication line such as a LAN. Thus, the data is taken into the screen printer 2 and stored in the storage unit 72 of the control device 70.

  Further, steps S807 to S809 and S812 in FIG. 8 are performed in a print inspection apparatus independent of the screen printing machine 2 or the printing apparatus. That is, an inspection trial result is displayed on a display device provided in the screen printing machine 2 or the print inspection apparatus, and is input via a known input device such as a keyboard or a mouse provided in the screen printing machine 2 or the print inspection apparatus. The inspection data is corrected by the user, or the inspection data is automatically corrected by a program stored in advance in the storage unit 72 based on the inspection trial result. The inspection data finally corrected is registered in the library 72a, and the printing process shown in FIGS. 4 and 7 and the printing inspection in a broad sense are performed.
