Field reliability prediction based on degradation data and environmental data

Abstract

This paper outlines a method that can be used for field reliability prediction using degradation data and environmental data. From different perspectives about the effects of dynamic environment on field reliability, we proposed two methods to relate the environmental variables to degradation process. The modeling technique and estimation method are illustrated by an example to predict the field failure time distribution of a product. The result of this study shows that it is possible to predict field performance by using ADT results, if done carefully and with good characterization of field environmental conditions.
