  • Patent number: 5429738
    Abstract: A method and apparatus for continuously forming primed circuits, the apparatus including a cylindrical drum rotatable about a generally vertical axis and a tank for holding an electrolytic plating solution. The tank is dimensioned to surround a lower portion of the drum and immerse the lower portion of the drum in the electrolytic plating solution. Means for introducing electrolytic solution into the tank are provided, and a plurality of metallic anodes are disposed within the tank surrounding and facing the lower portion of the drum defining a generally uniform gap therebetween. A plurality of cathodes are disposed above the tank and facing an upper portion of the drum, the cathodes being biased toward the drum. The apparatus is adapted to receive a movable continuous flexible web having a thin layer of conductive metal on one side thereof. The metal layer is masked to expose a plurality of patterns aligned along the web and a continuous strip of exposed metal along one edge of the web.
