Applied Engineering on Physics-of-Healthy and SHM of Microelectronic Equipment for Aeronautic, Space, Automotive and Transport Operations

Failure mode and effect analysis is a method for reliability analysis that tries to assess and identify existing failure modes of a system. This chapter presents a case study on application for automotive and aerospace. It shows how the activation energy is related to the stress and temperature applied and proof that the activation energy can no longer be considered as constant to extrapolate some experiment under high stress to nominal mission operation. A predictor is an in situ measurable and quantifiable electrical parameter used to assess the healthiness of a component introduced in equipment. The chapter provides an overview on how to conduct the prognostic failure model methodology applied to a specific industrial case. It presents a method for predicting the failure rate, and thus the reliability of an electronic system by summing the failure rate of each known failure mechanism.
