Abstract
A method and apparatus for improving the integrity of metal plated composites is disclosed. Plating improvements are achieved by first irradiating a nickel plated substrate, prior to application of a noble metal plating layer, to smooth any surface discontinuities or irregularities. Excimer laser pulses, having a duration of less than 100 nanoseconds, are employed to partially liquefy the upper surface of the nickel plating on the substrate. This invention is compatible with conventional plating processes, such as electroplating.
