ABSTRACT:
Disclosed is a method and apparatus for achieving a uniform coating of metal, such as copper, on an insulating strip, such as polyimide. After activating the surface, the strip is passed through a plating cell which includes a pumped solution mixed with a gas to achieve frothing. A high current is supplied to the cathode, so a cooled cathode construction is provided to prevent burning of the strip. Further features of the apparatus include a means for splicing strips, and a cantilever beam cathode contact for improving the physical contact with the strip.
