Accelerated testing

Most manufacturers of electronic products like computers, home appliances offer a minimum of one year warranty on the product . They usually replace the faulty component or part without any charge to the customer , which is the main reason why customers prefer to purchase branded products.

However, electronic components are likely to fail when subjected to extreme conditions like heat and voltage fluctuations. So it is important to test the components and check their reliability before using them under these conditions.

Specialized firms have directed and guided electronics design and manufacturing companies to new test processes, reducing field returns by as much as 90%, and in the same process reduced test time from 96 hours of traditional "burn-in" to one hour of HASS.
This new approach created dramatic savings from reduced test time, faster time to market, faster recognition of latent manufacturing defects, reduced warranty costs, and lost sales from dissatisfied customers
