Abstract
An apparatus is disclosed having at least one cathode adapted to maintain a line of contact with at least one substrate surface during relative movement therebetween. There is at least one anode located in a spaced relationship to the cathode and an electronically insulating member located between the at least one anode and the at least one cathode adapted to provide a gap between the substrate surface and the insulating member. When placed in a plating bath, the electric field is directed toward conducting patterns on a substrate to uniformly plate the patterns while minimizing plating on the electrode. The same device may also be used for electroetching by reversing the polarity of the electrodes.
