Abstract

The pinning of metallized ceramic substrates involves the insertion of copper pins into ceramic wafers having evenly-sp holes on predetermined centers and swaging the pins. Critical tolerances, typically in millionths of an inch, for the ceramic hole diameter and location conditions must be maintained. An inspection standard that uses a chrome glass technique to measure these conditions for raw ceramic product is accomplished as follows.
