TENTATIVE STUDY ON ACCELERATED DEGRADATION TESTING OF SPACE-USED FOG

摘要：

In view of the characteristics that the space-used FOG has long life and high reliability, accelerated degradation testing (ADT) was utilized to evaluate their reliability and life. Firstly, key technologies which are accelerated model and estimation were proposed. Then, SLD was confirmed as the weak point according to the field failure information. Therefore, system accelerated degradation testing was converted to part level. Finally, the scheme of the ADT which adopted step temperature stress was given. The methodology in this paper was demonstrated and validated by degradation trend of the light power during the test.
