Abstract

PURPOSE:To make the peripheral area of a hole thin and to obtain good yields by making a required area thin by cutting and more further thin by press, and then by carrying out a perforation at the central part. CONSTITUTION:The thickness of the peripheral part of a place to be perforated on a base plate is thinned by lathe cutting. Next, a small dead hole is made at a place to be perforated. In a smaller part than the area where cutting coining is carried out, press coining should be performed. Perforation process is carried out at the central part of the coining. Through the above process, a control electrode can be processed with a very high yield rate in a base plate more than 0.2mm. thick and a plate 0.005mm. thick around the hole.
