DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a printed wiring board wiring inspection device, and more particularly to a printed wiring board wiring inspection jig.

[Prior Art] Conventionally, as shown in FIG. 4, the inspection jig of this type of inspection device is placed on the inspection pin 25 of the printed wiring board wiring inspection device so as to match the inspection pin 25. A mesh plate 9 provided with grid-like through holes 19 at a pitch defined in the X and Y directions.
And a dedicated plate 8 having inspection through-holes 18 at wiring inspection points such as through holes of a printed wiring board, and a fixing jig for fixing the mesh plate 9 and the dedicated plate 8 in parallel at a constant distance. 20 and
It is composed of contact pins 7 inserted into both the inspection through holes 18 of the dedicated plate 8 and the grid-like through holes 19 of the mesh plate 9 so as to have a one-to-one correspondence. The contact pin 7 was inserted toward the 9 side, and the inspection through hole 18 of the dedicated plate 8 and the grid-like through hole 19 of the mesh plate 9 were made to correspond one to one.
In addition, the inspection through holes 18 of the dedicated plate 8 have an arbitrary pitch in both the X and Y directions, and the grid-like through holes 19 of the mesh plate 9 have a pitch defined in the X and Y directions. Since there are many grid-like through holes 19 in the mesh plate 9 that can correspond to the inspection through-holes 18 in the plate 8 one by one, a person selects an arbitrary grid-like through hole 19 and inserts the contact pin 7. The printed wiring board wiring inspection jig 10 was created. Further, in order to perform address conversion of the grid-like through holes 19 of the mesh plate 9 corresponding to the one-to-one correspondence with the inspection through holes 18 of the special board 8 of the printed wiring board wiring inspection jig 10 thus created, printing is performed. The printed wiring board wiring inspection tool 10 is placed on the inspection pin 25 of the wiring board wiring inspection machine, and the defect detection probe 26 is brought into contact with the contact pin 7 of the printed wiring board wiring inspection tool 10 to display the address conversion table. I was working on it. Further, in order to detect the defective position of the printed wiring board 27, the printed wiring board wiring inspection jig 10 is mounted on the inspection pin 25 of the printed wiring board wiring inspection machine.
Place the defect detection probe 26 on the printed wiring board wiring inspection jig
The defective position on the printed wiring board wiring inspection jig 10 is detected by making contact with the contact pin 7 of 10 and then the defective position of the corresponding printed wiring board 27 is detected, or by using the above address conversion table. The defective position of the printed wiring board 27 was detected.
