Abstract

A copper foil having multiple layers thereon is provided by electrodepositing an arsenic-containing copper layer thinly on at least one surface of a copper foil; further electrodepositing thinly thereon, a treated layer consisting of zinc and tin or consisting of an alloy of at least one of zinc and tin together with copper; and causing the metals of the respective layers to diffusion- permeate e.g. by heating through each other to thereby form alloy compositions in the vicinities of the boundaries of the respective layers. The resulting copper foil for printed circuits is superior in the adhesion-retainability between the respective treated layers. The foil may be first electrodeposited with a fine particulate copper layer, then a smooth copper layer, prior to the arsenic-containing copper layer. The outermost layer may be treated with a chromate (e.g. chromium electroplated) or an organic anti-oxidising agent. [GB2030176A]
