Despite the less than stellar support for the concept, I'm going to go ahead and try it anyway. I found a company in CA that makes 2 different types of epoxy, just for this purpose. The guy says it will work and the curing time is short and not temperature sensitive (unlike solder paste).

He's sensing me samples of both types although the spec's aren't available due to translation problems (the stuff is imported, and no English translation of the spec sheets exists).

I'm going to give it a try on through hole components first, then will play with some smt once I get some experience under my belt.

I'll post a message with the results back here is there is any interest.

I read in sci.electronics.design that TRABEM

Hopefully they've taken the time to write / translate / send you an MSDS for it...

About 10 years ago there was considerable attention to this is the press. We looked into it and didn't find anything which looked promising and neither did the industry. For non critical circuitry, I suspect there is possibilities

My idea (which was chuckeled at) was " conductive Velcro" Make parts with the loops and boards with the hooks. Easy repair, eh? Zip off the old, stuff on the new... No heat, no time to cure...

Imagine a demo of this compared to solder in the early days...

Let's look at the options for electronics assembly. Well you have two choices:

1- Dip everything in molten lead. 2- stuff 'n go.

Which do you pick...Hmmm difficult chioce, eh?

Ther ewas also something called "particle interface". Many small sharp conductive points on the PCB, but how to anchor the parts. This was intended for test fixtures.

In a production line they would probably use UV curing epoxies. They already do, but not for solder substitute.
