な接続をすることができるものである。The present invention will be explained in detail below with reference to Examples. The flexible printed wiring board 1 is made by providing a circuit 11 on one or both sides of a lexical board 10 formed of a visible insulating film or the like by etching metal foil or the like. , as shown in FIG. 2, a flexible printed wiring board 1
A terminal portion 2 connected to each circuit 11 is provided on the surface of the end portion by etching metal foil or the like. Further, the wiring board 3 is used as a motherboard to mount various electronic and electrical parts, and is sometimes formed by processing a copper-clad laminate or the like to provide a circuit 14 thereon. The wiring board 3 is formed with a connecting terminal portion 15 connected to the circuit 14 for connection to the 7-lexiple printed wiring board 1. In order to connect the end of the flexible printed wiring board 1 to the wiring board 3, as shown in Figure WS1, the end of the flexible printed wiring board 1 is bent and folded back so that the terminal part 2 is on the outside. Each terminal part 2 at the tip
This is done by contacting each connecting terminal part 15 of the wiring board 3, and in this state, soldering 4 from each connecting terminal part 15 to the terminal part 2 of the bent part of the flexible printed wiring board 1. By bending the flexible printed wiring board 1 in this way, 7
The terminal portion 2 exists above and below the bent end surface of the flexible printed wiring board 1, and the solder 4 can be bonded to the terminal portion 2 over a wide area along the upper and lower sides of the bent portion. . Therefore, since the bonding area between the terminal portion 2 and the solder 4 becomes larger, the bonding strength between the solder 4 and the flexible printed wiring board 1 can be increased, and the solder 4 between the wiring board 3 and the flexible printed wiring board 1 can be increased. It is possible to increase the connection strength and make a reliable connection.

Since the soldering is applied to the outer surface of the bent part of the flexible printed wiring board, the terminal part exists above and below the bent end face of the flexible printed wiring board, and the terminal part exists along the upper and lower sides of the bent part. This allows solder to be bonded over a wide area, increasing the bonding area between the terminal and the solder to increase the bonding strength, and connecting the wiring board and the flexible printed wiring board with high strength by soldering. It is something that can be done.
