摘要： Conductive circuits are formed by first metallizing a surface of a molded synthetic resin substrate to form an electrically conductive metallic film coating thereon of a thickness (e.g., between 0.2 to 2 .mu.m) effective to exhibit sufficient electrical conductivity for subsequent electroplating thereon. Non-circuit portions of the metallic film coating are thereafter removed with laser light so as to expose an underlying surface portion of the substrate and thereby form a circuit pattern on the substrate surface which is established by a portion of the metallic film remaining on the substrate surface. An additional metal layer may then be electroplated directly onto the remaining portion of the metallic film to thereby form the conductive circuit.
