It is possible to further minimize early life failures by performing accelerated life tests (like burn-in or IDDQ testing) which are done as a part of Texas Instruments (TI) outgoing test in the factory. ctsmonproWebThe useful life failure rate is based on the exponential life distribution. The failure rate typically decreases slightly over early life, then stabilizes until wear-out which shows an increasing failure rate. This should occur beyond useful life.
