MEMS扫描镜温度可靠性测试
摘要
温度是MEMS扫描镜的一个重要失效因素。研究温度对MEMS扫描镜振幅的影响
再通过温度冲击试验和高低温存储试验测试温度对MEMS扫描镜可靠性的影响
分析扫描镜在试验中是否失效和失效的原因。试验结果表明:高温对MEMS扫描镜外框架和镜面振幅无影响
低温对MEMS扫描镜外框架振幅影响较大
增幅达12.3%
对镜面振幅无影响;低温存储由于水汽凝结会导致MEMS扫描镜失效
高温存储对MEMS扫描镜可靠性无影响。
Abstract
Temperature is an important factor in failure of MEMS scanning mirror.Influence of temperature on amplitude of MEMS scanning mirror is studied
through temperature shock
high and low temperature storage test
measure influence of temperature on reliability of MEMS scanning mirror and analyze reasons for failure.Experimental results show that high temperature has no effect on frame and amplitude of mirror surface
but low temperature has great effect on amplitude of frame of scanning mirror
increasing 12.3%
and has no effect on amplitude of mirror surface;due to water vapour condensation
low temperature storage will cause failure of MEMS scanning mirror
while high temperature storage has no effect on reliability of MEMS scanning mirror.
