Hi Jim,
While I would strongly question the purpose of a "burn-in" test comprising160
HRS @ 125ºC and 352 HRS @100ºC, neither will damage the PWB [think of PWB
bakes] or the SJs [the SJs will coarsen in their grain-structure--which they
would do anyway in about onne year on the shelf or in service--and the IMC
layers will grow some, but without any real negative effects].
What is your customer thinking? Well, maybe they not thinking at all.
