Abstract

PURPOSE:To enable design and manufacture of a double-sided mounting to be facilitated by providing a reinforcing plate for each surface of a flexible printed-circuit board and a proper window hole at the reinforcing plate and then exposing a terminal soldering surface. CONSTITUTION:Reinforcing plates 7 and 7' for each of front and rear surfaces of a flexible printed-circuit board 1 are made of an insulation material and are bonded to each side of the printed-circuit board. Each terminal 10 of switches 8 and 9 passes through terminal holes 11 and 11' which are provided on the reinforcing plates 7 and 7'. Window holes 12 and 12' which are provided at the reinforcing plates 7 and 7' allow the terminal 10 of a push button switch 9 and the terminal 10 of a slide switch 8 to be soldered to a printed-wiring portion 2 of the flexible printed-circuit board 1. Parts which are mounted to both sides of the flexible printed-circuit board are mounted to the reinforcing plates 7 and 7' at each side. The window holes 12 and 12' are provided at an region of the reinforcing plate of the other side which opposes a parts- mounting region on the reinforcing plate of one side, thus enabling restrictions when designing a printed-circuit wiring pattern to be reduced.
