The Application of Accelerated Testing Methods and Theory(HALT and HASS)

DDF13_Keven

QualMark培训资料与大家分享!
算是比较详细介绍HALT与HASS,主要突出了这个测试的好处,当然也有推销他们产品的嫌疑!
关于HALT的好处就不说了,缺点从其它的书籍看到一些,这里列举出来和大家讨论:
1)Lesssuccessfulformechanicalproducts,especiallylargesizes;
2)Reliabilityimprovementsnotasspectacularasclaimed;
3)Extendingeachstresstesttodestructlevelsorthefundamentallimitoftechnology(FLT)createsartificialfailuresthatmayneverbereplicatedinthefield;
4)Becomescost-andtime-prohibitivetoanalyzeeverystressfailuredowntorootcauseandcorrection;
5)Primaryrelianceisoneachstressbyitself;thenonjusttwostresses-thermalcyclingandvibration;
6)Largenumberofunitsrecommendedfortests;
7)HALTcyclerepeatedforeachdesignchange;
8)Unitsnotreturnedfromthefieldforfurtherfailureprobing;
9)Notcapableofreliabilityprediction;

对于第3)点,我是比较赞同的,我们研究在实际使用中永远不可能出现的失效,这样有意义吗?这样有点浪费时间和研发成本.HALT的理论基础支持可能还是欠缺.
