ABSTRACT:
A screen printing plate includes a plate body having a front surface and a rear surface. The plate body has a plurality of openings penetrating from the front surface to the rear surface and formed according to a preselected pattern. A recess is formed on the rear surface of the plate body so as to surround the opening. A separation wall defining the boundary of the opening and the recess is formed between this one opening and the recess. The spreading of the solder paste onto a surface to be printed around the opening and onto the rear surface of the printing plate is restricted by the recess when the paste is transferred onto the surface to be printed from the opening. The paste does not go beyond the boundary defined by the edge on the side of the recess.
