ABSTRACT:
A stencil plate is made by an electroplating process rather than a steel fabricated process. A resist material and a film are placed upon a matrix and by using conventional photoresist operations, a resist coating is formed on the matrix in the shape of the apertures to be formed in the stencil plate. Metal is electroplated on the upper surface of the matrix and around the shaped resist material forming a stencil plate.
In some areas, a narrow strip of material must be deposited and overplating occurs. Supplemental open areas adjacent the narrow strips to be plated form removable slugs of plating material which help eliminate the overplating in the narrow strip areas.
