Abstract

PURPOSE:To provide an inexpensive and reliable circuit board for a watch by coating the most external profile of the circuit board insert molded by flexible printed coating (FPC) bonded with an IC with molding resin. CONSTITUTION:Flexible printed coating (FPC) 2 is insert molded by thermoplastic resin to enclose an IC 10. Containers 3, 8 and 14 for accommodating other elements forming an electronic watch are simultaneously molded to produce a circuit board 1 for the watch. In order to strengthen the adherence between the FPC 2 and the thermoplastic resin, an opening is perforated at the external profile of the FPC 2 partially with connecting portion 2c retained as designated by two-dotted broken lines. The external profile is so molded as to be coated with the resin when insert molding the circuit board.
