Printed-circuit module having a printed-circuit board mounted to a printing wiring board

摘要

A printed-circuit board module comprises: a flexible printed-circuit (FPC) sheet (25) with its two opposite end portions bent toward the side on which parts (24) are mounted and having connection terminals (29) formed side by side along marginal edges of the bend end portions; a printed-wiring board (22) having an opening (26) for receiving the parts (24) and connecting conductor patterns (27) formed in the neighborhood of the opening (26); and a fixing frame (23). The FPC sheet (25) is fixedly held by the fixing frame (23) and is mounted on the printed-wiring board (22) with the fixing frame (23) held therebetween. The FPC sheet (25) makes direct electrical connections to the printed-wiring board (22), and the amount of extension of the parts (24) into the opening (26) can be adjusted by changing the thickness of the fixing frame (23).
