Dormancy and Power On-Off Cycling Effects on Electronic Equipment and Part Reliability.

摘要

Two 12-month programs were conducted. The first was to collect,study,and analyze reliability information and data on dormant military electronic equipment and parts and to develop current dormant failure rates,factors,and prediction techniques. The second was to collect,study,and analyze reliability information and data on military electronic systems subjected to power on-off cycling,to correlate failure incidence with power on-off cycling,and to quantify power on-off cycling effects with respect to the dormancy and operating states. The data was processed and presented in the form of dormant and cyclic failure rates and factors by part types and subtypes for various part classes. Dormancy failure rate and cyclic ratio factor charts were constructed and partially validated. Environmental effects on the various part classes are discussed,together with factors relating them to one another in other energy states. (Author)
