Abstract:

The Small End-Skip evaluation has resulted in the elimination of small end-skips as a reject category. Another reject category which has been eliminated is Rough Edge Termination. Investigations are being undertaken to determine the causes of film spots. Although no detrimental effects were found from narrow spiral path widths, it was found that slightly lower yields resulted. Two process changes have resulted from the reevaluation of Electrical Tests and Tolerances. One was a Magnification Tolerance and the other was a Resistance Tolerance specification at 1st Consolidation. Syntron Feeding and Ultrasonic Cleaning of leadless ceramics were evaluated after a satisfactory spiralling chuck was designed. The tests were carried to completion by processing and evaluating all subsequent operations. Author
