Abstract

A technique is described whereby a lapping process is automatically implemented so as to maintain accuracy and consistency in the production of electronic print heads. Print heads are manufactured by encapsulating a printed circuit card in a plastic material. Precisely positioned electrodes on the printed circuit card must be accurately processed so as to make proper connection to electronic typewriters or printers. In prior art it was necessary to manually lap and test individual parts. Often it was necessary to do this process repeatedly so as to obtain the required results. To eliminate this repetitive process and to maintain accuracy and consistency, the technique described herein was designed to automatically provide the required lapping of print heads electronically.
