ABSTRACT:
A portable drum machine for producing electrodeposited copper foil continuously is disclosed. The drum machine has an electrolyte supply system which supplies copper ions at a substantially uniform composition. The machine produces copper foil that may be taken directly to a foil surface treatment system or rolled for treatment later. The result is a readily replicable, highly standardized computer-aided design stored on discs or in computer memory. A drum of readily fabricated design is made of three different metals designed for minimum voltage loss and uniform current distribution. The machine also incorporates a dimensionally stable anode precision-produced by ring-rolling concentric with the drum. Low-loss electrical connections are symmetrically configured. A spray reactor is provided for dissolving scrap metal or foil scrap. The system can be electrically and chemically isolated from other machines. There is also apparatus for thoroughly washing the foil with electrolyte and water. A directly coupled positive drum drive is coordinated with a controlled-tension windup of foil in roll form.
