Should Reliability Engineers Encourage Component Derating?
Kirk and Fred discussing the issue of derating components to increase the reliability of the larger system. Although Fred and Kirk agree on most reliability topics, derating by the traditional reliability guidebooks is not one of them.
Join Kirk and Fred as they discuss Fred’s recent article on the latest revision of the Certified Reliability Engineering (CRE) body of knowledge and in particular the issue of derating compenents.
- The rapid technological obsolescence of most electronics makes the life entitlement of components less critical as they have more life than needed for most applications
- Component manufacturers do not publish thermal operation margin between operation and what they are capable of, especially for semiconductors.
- The use of HALT to do empirical derating based on finding the weakest component and increasing that components capability, instead of shotgun derating based on traditional tables.
Enjoy an episode of Speaking of Reliability. Where you can join friends as they discuss reliability topics. Join us as we discuss topics ranging from design for reliability techniques, to field data analysis approaches.
