Abstract

Production of thin metal foil with a smooth and a rough side is effected by an electrolytic method using a slowly rotating cathode roller with a passivated Cr surface, which is a replica of the required rough surface of the foil, which is 50% immersed in an acidic Cu electrolyte employing consumable Cu anodes. The foil is continuously removed from the surface of the cylinder. The outer smooth surface is produced by suitable additions to the electrolyte. The method is employed for the production of Cu foil of less than 20 mu thickness for printed circuit applications.
