The Small Spiral End-Skip evaluation had progressed to where units have been placed on life test. Although no detrimental performance effects have been noted, End Skips do contribute to yield losses because they are out of tolerance. The Initial Termination Width experiments were completed and new limits for acceptable termination width established. Expanded experiments are in process and are directed towards the elimination of Termination Inspection. Designs were completed for the Sub-assembly Machine, Termination Inspection Machine, and Sequential glass Sealing Machine. The first leadless spiralling group exceeded an acceptable tolerance span. They are, however, being processed to completion for life testing. A second group of units are being processed on equipment modified to produce a better tolerance span and more uniform product. Author
