摘要
宇航元器件极限评估是一种新的可靠性评价技术,其目的是评价电子元器件的极限能力,以适应航天对电子元器件的高可靠性要求。介绍了极限评估和极限评估试验,提出了极限评估试验剖面设计的一般原则,给出了试验剖面设计的典型方法,并以微波固态功放的温度应力极限评估试验和GaAs单片微波集成电路的电压应力极限评估试验作为典型样例设计了试验剖面,通过试验验证了剖面的有效性,最后总结了极限评估试验剖面设计中应当注意的一些事项。
Aero-components＇ limit assessment, aiming at assessing the limit ability of electronic components in order to satisfy the high reliability requirement for aero-components, is a new technology for reliability evaluation. Limit assessment and limit assessment tests are introduced, and some general principles of screen design of limit assessment tests are proposed. Then the screens of two limit assessment tests are presented. The two tests, temperature stress limit assessment test of microwave solid power amplifiers and Microwave Integrated Circuit） are carried and proved the voltage stress limit assessment test of GaAs MMIC （Monolithic validity of the screens. The typical methods of screen design are also presented. Finally, some suggestions for the screen design of aero-components＇ limit assessment tests are given
