Abstract
A method of cleaning a metal surface by means of a laser to improve the surface characteristics, prior to plating thereover with a noble metal, such as gold. More particularly, the method hereof includes the steps of illuminating the desired areas of said metal surface with a laser beam; provided, however, the laser power density is controlled to vaporize surface contaminants and embedded foreign materials, without significantly altering the properties of the metal, in preparation for plating said cleaned areas with said noble metal.
