摘要
分析了3种金属桥材料在规定的环境条件下,所产生的热应变、热应力对可靠性的影响和金属桥失效的机理,并通过试验验证了金属桥连接的可靠性。
The failure mechanism and effects of thermal stress and thermal strain on the reliability of three kinds of metal bridge materials caused under certain environmental conditions are analyzed. The reliability of the metal bridge connection is proved by experiments.
