Abstract
A method for manufacturing solderable, temperable thin film tracks which do not contain precious metal on an electrically non-conductive substrate serving as a carrier employs the steps of applying an adhesive or resistance layer to the substrate, which serves as an intermediate layer, applying a conductive layer over the intermediate layer, and applying a protective anti-corrosion layer over the conductive layer. The protective layer may consist of aluminum or an aluminum alloy, or may be comprised of a combination of a layer of aluminum and a layer of chrome. An aluminum layer may also be applied between the intermediate layer and the conductive layer.
