摘　　要：据统计,武器型号在研制生产过程由元器件失效引发的质量问题时有发生。而大量元器件的使用失效由冲击环境造成,冲击对元器件的危害往往是致命的,引脚断裂,焊点脱落,器件腔体出现形变等等。因此型号在设计阶段必须考虑产品的冲击可靠性,比如产品级的冲击防护,类似保护箱,阻尼装置,吸能装置等,但这些产品级的防护不能完全保护元器件的可靠性。而近年来,电子元器件也朝着大规模,高集成化,小型化发展,新工艺,新材料也在不断应用,因此元器件在冲击环境下的可靠性保障工作也变得越来越有挑战性。Massive quality problems were caused by component failures because of impact environment during the developing and producting process of weapons, the shock such as pin breaks, solder joints fall off, cavity deformation and so on was fatal, so we must consider the shock reliability of weaponry during its design stage, like safe box, damping device, absorbing energy apparatus, etc. But these protects can not completely ensure the reliability of components, in addition, electronic components also developed toward large-scale, highly integrated, small-package with new technology and new materials in recent years, these change may make shock reliability of components more and more challengeable for our designers and researchers.
