Steve,

You will get that hour back in November....

In a prior company we used conductive adhesives for die attach to thick film ceramic substrates for hermetically sealed hybrid devices. Wire bonds for the rest of the connections. Fun stuff. 

Saw the other comments on the stuff not holding up in non hermetic applications. 

I wonder if conformal coating ove rit would help?
