Lifetime refers to the course of a life: being born, growing, blossoming to bear fruit, and returning to the soil. A human’s lifetime consists of three periods of life cycle – infancy/early childhood, young and middle adulthood, and old age. Figure 1. Three stages of human life cycle.

http://www.aecouncil.com/Documents/AEC_Q100_Rev_G_Base_Document.pdf 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.

WebA beta equal to 1 models a constant failure rate, as in the normal life period. And a beta greater than 1 models an increasing failure rate, as during wear-out. There are several ways to view this distribution, including probability plots, survival plots and failure rate versus time plots. The bathtub curve is a failure rate vs. time plot.

WebThe 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.
