End of life test

from Wikipedia, the free encyclopedia

The end of life test (abbreviation EOL test) is used to describe reliability tests that determine the technological limits of a component. This can mean that, for example, electronic components are exposed to certain loads such as high temperature, humidity or temperature changes until they suffer a total failure, e.g. B. with the Highly Accelerated Life Test . The aim is to determine the typical service life of a system and thus to determine the course of the bathtub curve . An alternative is to define a change in a measurable observable as a failure criterion instead of a total failure. An evaluation can take place , among other things, by means of a Weibull distribution . This system is, among other things, an integral part of Design for Reliability methods, such as the Robustness Validation method for the qualification of semiconductor components .
