Webearly life period (tELF): The specified early life period as defined by the user or the supplier. failure rate (λ): The fraction of a population that fails within a specified interval, divided by that interval. NOTE The statistical upper limit estimate of the failure rate is usually calculated using the chi-squared function. Web• Early life failures (also known as infant mortality): characterized by a relatively higher initial failure rate, which reduces rapidly. 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.
