High accelerated life test
[project details]
1.HALT (highly accelerated life test): Highly accelerated life test is a kind of found defects in the design process, by accelerating setting incremental stress accelerated exposure test sample defects and weak points, and then exposed to defects and faults from design, process and material aspects of analysis and improvement, so as to improve the reliability, the biggest feature is set higher than the designed sample run limit environmental stress, resulting from the exposure time is much shorter than the normal fault reliability time required under the condition of force.
2.HASS (high speed stress screening): Highly, accelerated, stress, screen is the product through the HALT test, operation or damage limit, in the production line to do high acceleration stress screening. Require 100% of the products to participate in screening. The purpose is to make the defect products do not exist any risks or at least in the product has not before leaving the factory to find and solve these problems, HASS is accelerated by stress in order to find the defective products in a short period of time, shorten the period of corrective measures, and find the same problem with the product.
3.HASA (accelerated accelerated stress sampling screening): Highly, accelerated, stress, audit is a screening test method using sampling theory in the mass production stage of products. It prevents defective products from being delivered to the customer's hands.
