How hot should silicon run?

I think you're living in fairy land

Hi Nigel - I respect your opinion and thank you for your feedback. What you have just said backs up what I said - although the silicon itself is reliable, it is everything else in the ecosystem that will kill your circuit as a result of high temperature. The point I am making is that temperature will not kill the silicon. However, increased temperature causes other problems (increased mechanical stress etc) and it is these factors that kill the circuit not the silicon.

I agree that most circuit die through EOS (electrical over stress), but this is a different failure mechanism completely. This post is related to temperature and its effect on the lifetime of a circuit, not electrical overstress

By your calculations, any device with 12 chips on board will last 60 days

If it was designed using devices manufactured in the 1990's and run at 125 degC continually for 60 days, it probably would fail. I think the laugh is on you
