US 2022/0091178 A1 · PRINTED CIRCUIT BOARD

Abstract

It is an object of the present invention to provide a printed circuit board capable of accurately detecting disconnections of circuit patterns with an automatic circuit pattern inspecting device even when positions of mounting lands are slightly deviated from normal positions due to manufacturing errors. For solving this object, the printed circuit board of the present invention is provided with a first mounting land 4a and a second mounting land 4b, and a first circuit pattern 6a and a second circuit pattern 6b on a surface thereof, wherein a first electric checker land 10a and a second checker land 10b which are electrically connected with the first mounting land 4a and the second mounting land 4b are provided on a surface of a wiring board 2.
