MODERATE PRECISION GLASS ENCLOSED CRYSTAL UNITS.
Abstract
This program is aimed at establishing a pro duction source capable of mass producing a semi precision quartz crystal unit in an evacuated glass holder. When attempting to manufacture a semi-precision crystal unit, several items must be considered and reappraised in the light of generally tighter performance tolerances. This reappraisal generally leads to tightening of manufacturing controls and tolerances. Conven tional methods of quartz orientation, sawing, dicing, dimensioning and lapping will be used to obtain a suitable quartz plato. (Author)
