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...
