The gotcha is that an IC is die coated and a MEMS oscillator likely is not. They should get packaged accordingly (= a low leakage package). Getting anything into a package at normal atmospheric pressure … not so much.

My bet still would be on a tool or die that was a bit past it’s “back to the shop for a touch up” point though. Bob > On Feb 14, 2019, at 11:18 PM, Bruce Griffiths wrote: > > NPT or BSPT pipe thread perhaps?

I blame the temperature hysteresis on the die attach to the lead frame which seems to be usually a silver filled epoxy compound. I hope that the hysteresis on a discrete zener is much lower. With best regards Andreas

Mount 8 die to ceramic substrate, mount those to Rogers boards. Thermal wasn't really an issue as everything was bathed in Flourinert™. Was an interesting project. The Unix kernel scheduler had to make scheduling decisions based on all the usual criteria plus how far away the free CPU and/or memory was.

You may not die from it buy it is crippling . He told me he got while fishing for stripers down by the shore . And he could no longer walk ...not sure if he was ever able to again since the person I knew who was in the same rehab was discharged before he was . .wasn't sure if everyone knew just how serious that virus is . He told me it attacks your brain .
