Abstract

PURPOSE:To reduce a distance between probes, and also to make it unnecessary to provide a press part for making the probe contact, by providing the probe on one side face of a flexible film, and providing a pressure working part on the reverse side face. CONSTITUTION:A printed circuit board 11 to be checked is placed in a roughly contact state in the lower part of a checker 100 for a printed circuit board. Subsequently, a pattern data 10 to be checked is inputted to a control part 13. Also, a pressure working part 5 is operated by operating a pump 6, a flexible film 2 is projected, and the probe 3 is pressed and made to contact lightly against the circuit board 11. In this state, the conduction of the wiring pattern 12 of the circuit board 11 is checked, and its result is displayed on the display part 14 of the control part 13. A projecting operation for making the probe 3 contact is not executed by a spring but by the pressure of the working part 5, by which the distance between the probes 3 becomes small. Also, the press part for making the contact 3 contact becomes unnecessary.

(c) Problems to be solved by the invention However, in the pudding mill wiring board checker (100a) whose main part is shown in FIG. 12, the wiring pattern (12a)
The distance between! There was a problem in that t(4a) could only be used with the same printed wiring board (lla)f as the contactor (3a). In other words, if the shape of the wiring pattern (128) is different, each printed wiring board requires a print 1 to a wiring board checker C. In particular, in recent years
There was a strong tendency towards domestic production, and the above problems were serious.
