Abstract

Continuous metallic films are coated on nonmetallic substrates by many techniques. Included among these coating techniques are electro-plating, electroless plating, vacuum deposition, sputtering and gas plating. Subsequent removal of such metallic films from a substrate, for salvage or testing purposes for example, is sometimes desired. Separation of the plated metallic film from a substrate is obtained quickly and efficiently by preferential heating of the film. Placing the film in contact with an element having a temperature in the range of about 200 degrees C to about 300 degrees C causes immediate separation of the film from the substrate. When the coated item is flat, a hot plate can be used as the heated element.
