Essentially any time you see ceramic packages they are either US or Russian military where cost is not a consideration. Aerospace is very similar in their requirements for ruggedness and performance over temperature swings, so often end up using the same packed chips as the military rather than consumer level ones. Lots of early medical electronics like pacemakers seem to use military spec packages as well, presumably just because they are in a space where you can't really dig them out easily and replace some faulty consumer grade 74 series logic.
- ufmace 11y agoI think I saw some of those when I was working with guys who designed oilfield tools. It was always a challenge to find stuff with a decent MTBF in the 150C+ oilwell environment. IIRC, there was no published info on it, so we bought a ton of different brands and models, tested them all in-house, and built tools with the ones that performed the best.
