Abstract:

Effort was continued to study factors that produce failures of quartz crystal units. The objectives of this study are 1 the determination of the causes of failure in quartz crystal units 2 the formulation of accelerated tests for the determination of time to first failure, meantime between failures, and life time 3 the evaluation of such factors as elevated temperatures, and drive levels other than the recommended drive levels, in causing failure of quartz crystal units and 4 the determination of a satisfactory definition of failure in terms of performance. Test methods and test results are presented.
