ABSTRACT:
A method is described for depositing an electroless copper plate onto a region of a styrene-derivative polymer surface using a vacuum deposited copper catalyst. Prior to depositing the catalyst, the region is treated with ultraviolet radiation while exposed to air. It is found that the vacuum-deposited copper is active to catalyze electroless deposition onto the treated region, but not upon a similar region not subjected to the ultraviolet treatment.
