Method for producing electrical circuits based on flexible conductor plates - has rear side of copper@ laminated flexible basic material connected to mechanically stable auxiliary carrier with low heat expansion

摘要

Prodn. of electronic circuits based on flexible conductor plates, uses plates with preformed conductor pattern structure being firmly connected to a mechanically stable auxiliary carrier having low heat expansion, which only after completed further processing of the flexible circuit, including soldering, is deformed and partly or completely further removed. The flexible basic material is pref. of polyester and the auxiliary carrier is of spring bronze - CuSn6. Through a partial removal and structuring of the auxiliary carrier, functional areas such as heat troughs, fixture aids or additional conductor paths are produced. USE/ADVANTAGE - For the prodn. at favourable cost of electronic circuits on the basis of flexible conductor plates.
