Abstract

PURPOSE:To easily peel aluminum and copper foils and to obtain the laminating material not peeled off in case of piercing, etc., by superposing aluminum and copper foils and cladding the both by executing cold rolling at the specified rolling reduction rate. CONSTITUTION:An Al foil and copper foil are facilitated and the one face of the Al foil is subjected to rough facing by a nylon made wire brush. The Al and copper foils are then superposed so that the rough face of the Al foil comes to the copper foil side and the both are clad with cold rolling at 40-60% reduction of area by a cold rolling mill. The scratch onto the copper foil 2 can surely be prevented at the forming time of a through hole 3 and in case of peeling the Al foil thereafter it can be simply peeled off and the working can be simplified.
