The products have been passed adequate burn-in procedure, their mean residual lifetime will be improved and their useful lifetime be longer than their guarantee period. The general application objective of burn-in are maximizing the mean residual lifetime and minimizing total cost which their contents had been studied. Meanwhile the tendency of the product with Weibull distribution characteristics of the mean residual lifetime after burn-in procedures had been studied. Furthermore the gain of mean residual lifetime and unit time gain of mean residual lifetime in variable burn-in time versus various parameters of products with Weibull distribution had been studied in order to explore the optimal burn-in time and the level of conditions.
