Here's a link to a Master-Bond pure silver conductive adhesive. I'm trying to get some info on it, but it appears to be a one part epoxy (no mixing) that is heat cured. It can be thinned with acetone. I'm thinking I could "draw" the circuit with my cnc router, then stick the components on the epoxy, the pop it into the oven to cure. Or, just cure the epoxy then solder the components. Any thoughts?
