Alumina Substrate Assembly Study.

Abstract

The potential exists for intermittent electrical failures as the result of the various mission environments experienced by the alumina substrate assemblies (ASAs) used in FLTSATCOM. To explore this possibility, a test program was devised in which samples of the ASA technology were subjected to a series of monitored vibration, mechanical shock, and thermal cycle environments that approximated those of the mission. The tests indicated that no failures could be directly attributed to the alumina substrate. Those few failures that did occur were more adequately explained in terms of other failure mechanisms. Therefore, it would appear that the ASA is a viable medium for FLTSATCOM modules when subjected to environments within the range of this study. (Author)
