    Abstract: A readily etchable printed circuit board is provided which comprises a resinous substrate having bonded to at least one surface thereof a composite metal structure. This metal structure includes a layer of copper foil having opposed first and second surfaces and a thin layer of nickel having opposed first and second surfaces with one of the surfaces of the copper foil being bonded to one of the surfaces of the nickel layer and the opposite opposed surface of the nickel layer being bonded to the resinous substrate with the nickel layer containing an effective amount of sulfur to render the copper foil and the nickel barrier layer mutually etchable, i.e., etchable by the same etchant. The preferred amount of sulfur ranges from about 0.05 to about 10.0 weight percent.

    Abstract: An improvement in providing a mechanically strippable copper plate on an aluminum carrier is achieved by pretreating the aluminum carrier with an alkaline, aqueous, alkali metal zincate composition containing a small amount of one or more water soluble iron, cobalt or nickel salts, and removing substantially all of the deposited zincate coating with acid prior to copper plating.
