Subject: Burn-in
Does burn in today buy you anything? We currently perform a static burn in with after burn test defects around 0.001%. Dynamic burn in has been suggested. What about HALT testing on prototypes and eliminating burn in on production lots. Any input would be much appreciated. Thanks, Mark

I agree with Bruce's comment. We discontinued burn-in several years ago (after discovering it's not effective in participating the types of defects that were escaping to the field). We recently implemented Highly Accelerated Stress Screening (HASS) which is based upon HALT results and it performed during production. We are having much beeter results finding defects in the factory as opposed to in the field. Mark
