Reliability Assessment of Passives for 300C using HALT

Abstract

Highly accelerated life testing (HALT) is used to quickly assess the reliability of passive components for geothermal applications operating at 300°C ambient temperature. The HALT methodology uses combined stresses to accelerate the failure of capacitors and resistors. This paper describes the test methodology, special fixture designed, and results on capacitors and resistors. Life models for the components are presented. A process to modify component terminations is presented to make them appropriate for 300°C.
