AGGREGATE PRINTED WIRING BOARD, PRINTED WIRING BOARD DEVICE, PRINT HEAD, AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To solve such a problem that part of coupling pieces is left on a printed wiring board device or part of the printed wiring board device is cut when cutting the coupling pieces on an aggregate printed wiring board including a plurality of printed wiring board devices connected via the coupling pieces. SOLUTION: The aggregate printed wiring board 1 includes a plurality of printed wiring boards 2 having conductor patterns formed of metallic foil layers 3 formed on its surface 17 where the boards are coupled via a plurality of the coupling pieces 4. Since the coupling piece 4 includes a recognition mark formed of the metallic film layer 3 on the surface 17, a cutting edge of the coupling piece 4 is positioned while being corrected by the recognition mark, and the coupling piece 4 can be removed from the printed wiring board 2 accurately by the cutting edge.
