USING CONDUCTIVE EPOXY: Epoxies do not bond well to tin or tin alloy surfaces. * For components: a silver-palladium or gold end termination is recommended. * For substrates: gold over nickel should work well. Remember epoxy is not hermetic, and ox

Sign makers utilize a material called "Scotch-Cal" and "Scotch-Brite" in making decals used in outdoor environments. Material similar to this comes in metallic silver and gold. Pieces of this can be economically die-cut and affixed to your PC Board

I have not looked into eutectic die attach. My dies are about .012" square and could get smaller. Currently using a Epoxytech conductive adhesive. I am going to go out and look at equipment and build samples. Some vendores state they can do .010"
