Development of impact-resistant quartz-crystal resonator in a standard microminiature UM-1 type package
We studied the structural characteristics of quartz-crystal resonators. Furthermore, we developed new technologies and used them in manufacturing the quartz-crystal resonators in a standard micro-miniature UM-1 type package, capable of withstanding high mechanical loads. Findings of the experiments show that these resonators can withstand three single strokes with shock acceleration peak value of 150 000, 200 000 and250 000 m/s2 and duration of the action of 0.1...0.5 ms in three directions
