  • Nickel/indium alloy and method of using same in the manufacture of printed circuit boards
    Patent number: 4686015
    Abstract: An improved method of manufacturing printed circuit boards of the type in which a metal clad substrate is covered with a photoresist, the photoresist is masked with a predetermined circuit image, the photoresist is exposed and the exposed photoresist is removed to provide a circuit image on the surface of the metal, the circuit image is electroplated with a metallic etch resist and the remaining photoresist and exposed metal cladding is removed to provide a board having a metal circuit covered by a metallic etch resist, the improvement comprising a metallic etch resist composed of a nickel/indium alloy containing from about 0.1 to about 10 weight percent indium based on the total weight of the alloy.
