の欠点がある。 Therefore, when the number n of identical unit circuit patterns included in a printed wiring board is large, the number of test pin sets 32 corresponding to a single circuit pattern is also large n.
As a result, the processing becomes complicated, and the test base plate 1 and the pin base plate 3 are required to have a large surface area with a large lateral spread, so the parallelism of both base plates 1 and 3 must be adjusted. There are drawbacks such as difficulty in coming out, and the guiding movement in the vicinity and in the direction of separation between the two also lacks smoothness.

At this time, the pin base plate 7 is set to be directly above the unit circuit pattern P 1 at the end of the printed wiring board 2. Next, the pin base plate drive device 7
2 is driven to lower the pin base plate 7, and a continuity test is performed on the first printed wiring section P1 in the same manner as in the conventional method as described above. If this continuity test passes, the next step will be taken. However, if there is a disconnection and crosstalk and the test fails, a signal from the test pin will command the marker actuator 81 to operate the marker 8, and it will be determined that the test has failed. An appropriate mark is placed on the printed wiring section P1 .

=16 unit circuit patterns are included, and if the test is carried out by first moving in the x-axis direction as described above, then the x-axis drive device 5 is moved 12 times including the positive and negative directions.
3 times, the y-axis drive device 6 is operated 3 times to test the test base plate 4.
By moving the entire printed wiring section P 1 ,
This completes the penetration test for P 2 ,...P 16 . In this example, test pins for two horizontally arranged printed wiring sections are provided protruding from the pin base plate 7, and two horizontally arranged printed wiring sections P 1 and P 2 are tested at one time. For example, the number of times the test table plate 4 is moved is four times in the x-axis direction and three times in the y-axis direction.

Test stand plate 4 equipped with positioning pins 41 for positioning by engaging with positioning holes drilled in
An x-axis drive device 5 and a y-axis drive device 6 drive the test stand board 4 in both the x and y directions, and the printed wiring board placed on the test stand board 4 is aligned in the x direction or the Y direction. For each unit movement, the test pins 71, . . . correspond to each terminal part of the unit circuit pattern.
A disconnected cross-wire detection pin base plate drive device 72 in which the implanted disconnected cross-wire detection pin base plate 7 lowers and rises at a fixed position relative to the floor surface, and repeatedly contacts and separates from each unit circuit pattern. and a defect mark is added to the surface of the unit circuit pattern by the disconnection/crossover signal of the unit circuit pattern which is arranged near the disconnection/crossover detection pin base plate 7 and detected by the test pins 71, . . . Since the device is configured to include a defect indicator display device 81 for detecting a defective circuit pattern, a large number of unit circuit pattern groups can be detected simply by reciprocating the disconnection/crossing detection pin base plate equipped with test pins corresponding to only one unit circuit pattern. A printed wiring board having a large area can be efficiently inspected. This makes it possible to reduce the size of the broken and cross-wire detection pin base plate, which eliminates the need for the complicated work of planting a large number of test pins.Furthermore, since marks are automatically added to defective locations, each unit circuit This has the effect of making it easier to separate out each pattern and identify defective products when shipping the product.
