Removable conductive epoxy

I am looking for a electrically conductive epoxy that can provide good contact for a Silicon chip gold-metalized backside at 10 GHz, for a month or two. Then I would want to disolve the epoxy (alcohol, acetone, etc) easily, or just peal off the chip mechanically, and allow the chip to be removed and reinstalled in a final circuit without damaging the backside metal.

In other words, I need something like a silver epoxy that never fully cures, but partially cures.

Thanks, Rich

I was hoping for something a little more thixotropic than just silver paint!

Rich,

Look at this Electro grease by McMaster Carr made for them by AI Technologies (but you can't find the same product at AIT website)

The part number is 1219K57. I have used it satisfactorily at 6GHz.
