られる。Conventionally, when testing continuity of a printed circuit board that is larger than the testing range of a continuity testing machine, the printed circuit board is divided into multiple pieces so that all of the nets within the circuit board can be tested for continuity, and the continuity testing is performed multiple times. Therefore, the inspection was complicated and required a lot of time. Although there is no one designed for this type of divided continuity test, for example, Japanese Patent Application Laid-Open No. 61-57864 does have a through-hole for testing.

題があった。In the above conventional technology, when testing the continuity of a printed circuit board that is larger than the testing range of the continuity testing machine, it is necessary to divide the board so that all the nets can be tested, and the number of divisions increases depending on the arrangement of the nets, resulting in an increase in testing man-hours. The problem was that it cost a lot of money.

検査用スルーホールを含む他方の分割領域を検査する。On a printed circuit board that is larger than the inspection range of the continuity tester, a through hole for inspection is installed in the middle of the pattern wiring that spans one divided area and the other divided area K, and at a position that is included in each divided area, at the printed pattern design stage. will be established. Then, during the continuity test, one divided area including the test through hole is tested using a continuity test machine. Next, the other divided area including the same inspection through hole is inspected.

゜7によシ検査される。As shown in FIG. 1, the divided continuity test method for printed circuit boards of the present invention is carried out at the printed pattern design stage by checking 1) on the pattern wiring 9 that covers both one divided area and the other divided area, and then One divided area of the printed circuit board 1, which has a through hole 4 for inspection at a position included in the figure, is first inspected. At this time, through hole 2
, the test pin 6 of the continuity tester is placed between the through holes 4 for inspection.
It is inspected according to ゜7.
