摘要：PURPOSE:To blow off a piercing pin in a fixed direction and make a hole at a specified position on a ceramic green sheet by supporting the piercing pin by two plate springs arranged parallel to each other. CONSTITUTION:A piercing pin 7 is supported by two plate springs 5, 6 arranged parallel to each other. Thus, even when the piercing pin 7 is blown off by elongating force of a piezo-electric device 2, its blowing direction is constantly fixed. As a result, a V-shaped tip of the piercing pin 7 blown by the piezo-electric device 2 collides with a ceramic green sheet 10 placed on an elastic plate (a plastic rubber sheet) 9, and sharply pierces through the plate. Like this, a hole can be exactly pierced at a specified position on the ceramic green sheet 10, and thus the yield of a ceramic multilayer wiring board can be improved.
