红外探测器用蓝宝石滤光片焊接工艺研究

摘要

To solve the problem of the low yield and the later failure of the soldering of Al2O3 sapphire optical filter and Kovar alloy,several influencing factors of the low field of the Al2O3 sapphire optical filter are analyzed and stud-ied. Aiming at these influencing factors,the solutions are proposed and its reliability has been verified through the ex-periments.%针对某型号探测器组件上用的Al2 O3蓝宝石滤光片与可伐冷头钎焊的成品率低、后期失效问题突出等问题展开研究，找到了影响滤光片焊接成品率的几个关键因素，并针对这些因素提出解决方案，并通过一系列环境试验验证其可靠性，大幅提升了宝石窗口密封焊接工艺成品率。
