Freescale Stress Test


Freescale performs accelerated stress testing during process certification to identify potential failure mechanisms and eliminate their root causes prior to product development. Stress tests are also performed during qualification of a product to check for potential failure mechanisms associated with integration of product design and process technologies. The following table outlines the major stress tests performed during process and product introduction. Other tests may be required for particular product types.
