Burn-in effectiveness-theory and measurement

Burn-in effectiveness is modeled as a function of time, temperature, electrical stress, stress coverage and failure mechanism. Actual field data for a variety of products is used to validate or deduce the relevant burn-in parameters. The modeling of burn-in is discussed to show the importance of the acceleration and stress coverage of the burn-in and of the failure distribution of the product. The modeling of burn-in is used to explain the failure characteristics of products which experience burn-in. The modeling of the characteristics of the failure distribution of burned-in product was used to analyze several experimental or reliability data sets to either validate or deduce the relevant parameter estimates for the specific burn-in. The modeling also extracts the relevant burn-in parameters from an analysis of field reliability performance.<
