FLEXIBLE WIRING BOARD AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a flexible wiring board allowed to be easily bent at a necessary position in the case of installing the wiring board on electronic equipment while the whole body of a conventional flexible wiring board tend to be easily bent and it is difficult to bend the wiring board at a specific position. SOLUTION: After forming a copper mask (16) having a slit whose width is narrow on an insulating film layer (12) which is the base of the flexible wiring board, the film is etched to form a half etching part (18b) on the board. Since the obtained flexible wiring board is easily bent at the formed half etching part (18b), bending processing at the necessary position can be extremely easily performed. COPYRIGHT: (C)2004,JPO
