Industrial Preparedness Study on Tighter Tolerance CR-(Xm-22)/U Crystal Units

Abstract

Multiple cutting was tried in an attempt to increase accuracy in sawing wafers. Using a Felker Saw for this investigation presented problems that were too numerous to pursue and yet justify this added effort on this contract. Efforts were then concentrated on increasing cutting accuracy using single blade operation on Felker Saws. It was found that the use of plywood blocks for mounting X sections and thin saw blades for cutting was responsible for a wide angular spread. It was then decided to try mounting X sections on Glass plates instead of wood and the use .045 inch thick saw blades instead of .025 inch thick blades. Results showed that the use of glass plates and thicker saw blades greatly increased cutting accuracy.
