摘要
The present invention relates to a treatment for improving the adhesive properties of metallic foils to be used in electrical and electronic applications. The treatment of the present invention comprises applying a light substantially uniform layer of metal to at least one surface of the metallic foil just prior to the formation of a plurality of dendritic structures on the surface. The metal layer renders the surface or surfaces to be treated more uniformly electrochemically active and consequently more receptive to the subsequent dendritic treatment. The treatment of the present invention has particular utility in improving the adhesive properties of wrought copper and copper alloy foils. An apparatus for performing the present treatment is also described.
