Subject: Re: [TN] high temp environment
Graham,
Back in the day, we would have approached as much as we could with hybrid technology.
Eutectic die attach on ceramic [High temp co-fired ceramic, alumina substrate within metal package, or Low Temp Co-fired ceramic], etc. Way back, there was even eutectic attach for passives - if properly metallized...
Being in a hermetic package, no conformal coatings...
Being a potentially highly corrosive environment the package is truly put to the test. Drawing upon implantable medical technologies [also a corrosive environment, believe it or not], there are multiple packaging options available including stainless & titanium.
Just a different persective...
