Study on the Reliability Problem of MEMS Fuze Mechanism

Article Preview

Abstract:

MEMS technology has become the hotspot of fuze development currently, but the reliability problems seriously influence the application of MEMS in fuze. By way of analyzing the characteristic of MEMS fuze mechanism in aspects of process technics, material behavior, structure form and micro size effect, it shows that the reliability of MEMS mechanism is quite different from the traditional fuze. The environment stress in full life cycle of fuze and the main failure mode of MEMS mechanism under environment stress have been analyzed, and the interrelated matrix between environment stress and failure mode has been presented. Based on these investigation, the reliability testing method of MEMS fuze mechanism has been studied, which can provide guidance for the reliability testing of MEMS fuze mechanism.
