Abstract

Gold exchange plating solutions, such as OROMERSE(Trademark of Technic, Inc. of Cranston, R I.) can be employed to plate directly onto insulating materials, such as ceramic and glass. This result is achieved by directing a high powered laser beam upon the surface to be coated. The laser is employed to heat the solution to its boiling point or above, only in locations where the solution contacts the surface of the insulator which is to be plated. In an experiment, we used a focussed continuous wave, 18-watt argon laser beam directed onto the surface of glass and alumina. As a result, we observed that a gold deposit was produced on the glass and alumina surfaces only in those regions where the laser was incident.
