Abstract

There is described a technique which applies a technology previously used in the production of novelty items to the manufacture of printed circuit boards. The technique comprises the following steps. The artwork is engraved on a steel plate. The coating material is caused to flood the plate, after which a doctor blade is used to remove most of the coating material. Some of the coating material remains in the pattern engraved on the plate. A silicone rubber pad with controlled resilience and surface tension is lowered onto the engraved plate. When the pad is raised, the coating material adheres to the pad in the pattern of the engraving. The pad is then applied to the printed circuit board.
