Aside from the resistivity of the epoxy, the largest problem I see

Plus, it makes it really messy for the salvagers/recyclers.

Hello John,

Aside from the resistivity of the epoxy, the largest problem I see
is throughput. That is, where are you going to store all those
boards while the epoxy is curing?

Then there is the stench that most epoxies let off. Mostly of the not so
healthy kind.

I do not know about Masterbonds conductive epoxy(ies), but i have
used silver conductive epoxy.
1) EXPENSIVE, 2) good for short-term and medium-term repair, but no
where as reliable as a solder connection.

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