文档名：密封电子元器件与装置多余物检测发展综述
摘要：密封电子元器件与装置作为航天系统中的重要组成部分,具有高精密性、高可靠性以及高复杂性的典型特点,而多余物问题是严重影响其高可靠性的主要因素之一.随着航天技术的快速发展,多余物检测技术也在不断改进与深入.该文以认识多余物、控制多余物产生以及检测多余物为主线,围绕多余物的防控方法、检测方法、检测标准进行综合论述.着重分析了检测方法中的颗粒碰撞噪声检测(PIND)方法,分别从小型元器件多余物检测、中大型装置多余物检测两个角度,针对现有研究进展逐一进行了详细的介绍.在此基础上,结合现有国内多余物检测研究的现状,针对多余物检测的难点与未来发展趋势进行归纳,并提出了期望与目标.
