The organization of a study of the field failure of electronic components

Abstract

This paper describes the organization that has been evolved for the collection and analysis of field failure data. A summary breakdown is given of the data collection organization, the Data Format and the methodology of Data Analysis. Preliminary studies show the system is working. The concept of superpopulation has been established in order to judge the relative importance of data as it is accumulated.

Reliability behaviour of electronic components as a function of time

“…The organization and some preliminary results have been discussed in several papers. [1][2][3] The detailed nature of the data collected has meant that as more data becomes available for each component type, it is possible to investigate the time dependent reliability behaviour of a range of electronic components based on field failure information. This method of presenting component behaviour examines the traditional constant failure rate assumption for electronic components as used in existing models for reliability p r e d i~t i o n .~-~…”

An event based database for the support of a holistic reliability assessment tool

“…Campbell et al in Ref. 6 describe the organisation that has been evolved for the collection and analysis of field failure data. The REMM database has been designed so that it can support the Bayesian methodology used by the REMM model.…”
