Would that be more when a burn-in cycle takes that components to close to the maximum threshold? If you degraded a componnet through processing then the burn-in would verify this.

JF,
Due to the increasing reliability of commercial components, some studies suggest that the stress during burn-in (handling, temperature, voltage) will not screen out any latent defects but will instead reduce the reliability of your product.

Subject: [TN] Burn-in
Are burn-in required on every units that come out of production or is it usually done on
a sampling basis? If it has to be done on every unit, why is that so? We're requested
to do it on all units, by contract. But some believe that is overkill... I'm among them.
Any thoughts???
Thanks in advance!
JF
