Ongoing reliability test
From Wikipedia, the free encyclopedia
The ongoing reliability test (ORT) is a hardware test process usually used in manufacturing to ensure that quality of the products is still of the same specifications as the day it first went to production or general availability.
The products currently in the manufacturing line are randomly picked everyday with a predefined percentage or numbers and then put in a burn-in chamber that matches the profile of the elevated temperature specifications. The profile must be enough to bring the product to early maturity, almost similar to the intentions of running the highly accelerated stress test except that the product life is just accelerated enough but not to its predicted end-of-life.
Quality of the products is then measured with the results of this test. If a unit fails, it goes under investigation to see if there was contamination... meaning some wrong or bad parts that were bought from other manufacturers are used which in result caused the problems on the product. If it is proven that a real failure occurs, the batch of units that were produced along with the failed unit, is then tagged for re-test or repair to either verify or fix the problem.
