ABSTRACT:
Circuit boards having excellent electrical and mechanical properties are obtained when special mixtures of polyarylene sulfides and polycarbonates, polyaryl ethers, polyamides, polyesters or rubber elastomers are used as base plates for the wet-chemical deposition of the circuits and the boards are treated with an oxidizing agent before activation.
