Abstract:
A method for manufacturing copper-resin composite materials, which comprises 1) affixing palladium or palladium-tin catalyst onto a resin substrate, 2) treating the resin substrate with affixed catalyst with an electroless copper plating bath comprising copper ions and reducing agent, without performing a catalyst acceleration treatment, to form a copper thin film on the resin substrate, 3) subjecting the resin substrate having said copper thin film to an electrolytic copper plating treatment prior to the formation of oxide film on the copper thin film surface of the resin substrate, to form a copper-resin composite intermediate material, (4) etching or polishing the copper-resin composite intermediate material, and 5) subjecting the etched or polished copper-resin composite intermediate material to an electrolytic copper plating treatment or pattern formation treatment to form the copper-resin composite material.
