Some of use don't believe in burn in at all for electronics. (For speakers, definately, but not for ICs.)

I work in a semiconductor fab. We don't do any special "burn in" for testing chips when they come out of the factory.

In fact, "time at temperature" is what we use for accelerated life testing. To failure. But people will believe what they want to believe...

Probably for the same reason that the higher priced component always gets a better review in the rags than the less expensive one. Or that a new audio format _always_ sounds better than the one it replaced.

OT warning.

Cool Kevin! What fab is in the states? IBM? (ASIC designer myself...)

jcmccorm- 10 years at Nasty, I mean National, and now 2 years at a little bitty placed called Micrel (we compete with companies like Maxim, Linear Tech, AMCC, PMC Sierra). Analog, mixed signal stuff.

Cool Kevin. I like Micrel. I designed in several of their voltage regulators onto PCBs this year. You da man!
