Abstract

The refurbishment of components that are returned from field system maintenance is common practice in the electronics industry. No refurbishment process is one hundred percent accurate and the potential for escapes exists. The potential from intermittent or latent faults that are detected in the refurbishment process makes the probability for a failure of a refurbished component slightly higher than a component that has not exhibited a failure previously. Disclosed is a method for accounting for this probability in real time recovery and isolation, system repair, and failure analysis for returned components.
