  • Three dimensional plating or etching process and masks therefor
    Patent number: 4985116
    Abstract: In a process for plating or etching metalization patterns on the surface of a three dimensional substrate, a flexible plastic mask is fabricated by first coating the surface of a thin plastic sheet with vacuum formable ink. The mask is then molded into the shape of the surface into which the pattern is to be formed. A low power YAG laser is used to remove areas of the ink through which light is to be allowed to pass. This mask may then be used in either a print and plate process or a print and etch process by drawing the mask into intimate contact with the workpiece by applying a vacuum between the mask and the workpiece. The workpiece may then be exposed to light through the clear areas of the mask.
