PRINTED CIRCUITS AND METHODS THEIR MANUFACTURE

摘要

This is directed to an electronic circuit apparatus using a flexible printed wiring board having a conductive leaf formed on the surfaces of a flexible base material such as phenol resin or the like, wherein a circuit conductive leaf is formed on at least the single face of a flexible base material and a peripheral edge leaf is formed on the periphery of the flexible base material. An electronic parts is mounted and connected to the circuit conductive leaf. Since the flexible base material is extremely thin and flexible, the electronic circuit apparatus can be constructed smaller and thinner.
