ABSTRACT

The ALT experimental design mentioned in section 2.1 of traditional process is not applicable to satellite unit due to its characteristics which mainly include the following aspects:

1. The sample size is small The manufacturing process is complex and

the cost is higher for satellite products, so the life test sample size is unlikely to be too large, especially for satellite unit. Sometimes only one product can be used for the life test. So it’s hard to get the acceleration coefficient of products by the method of assessment.
