COPPER FOIL WITH RESIN FOR LASER BEAM BORING AND ITS PRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide copper foil with a resin capable of laser beam boring in order to enable the adoption of a copper direct method which can use a conventional infrastructure directly and reduce costs by cutting a process and a method for producing the copper foil. SOLUTION: In the copper foil with the resin for laser beam boring, a surface layer of manganese and/or a manganese alloy is formed on the surface on the laser beam irradiation side of the copper foil.
