Quartz Crystal Units for High G Environment.

Abstract

The design of small quartz crystal units, operating at the fundamental mode frequency of 15 to 23 MHz, which will survive shock acceleration amplitudes of 15,000 g's and more is given. Test data on the number of failures and the permanent frequency change as a result of various levels of shock are shown. A new method of bonding the quartz resonator to the support, using electroplated nickel films with thickness of the order of 0.5 thousandths of an inch is discussed. Precautions in the processing of the quartz resonator are shown to be necessary to avoid destruction of the resonator at shock levels higher than 15,000 g's. (Author)
