Glue is designed to glue, finish to finish. Switching them around
never sounded good to me. If it was a good idea, glue makers or finish
makers would perfect it and sell it as a finish with known results.
They probably already have.


At the same time, there are products out there that work well completely
outside of the intended use. Sparkfun Electronics has a post about a $30
electric skillet they use for prototyping SMD PC boards. I've tried the
method--heat gun on the back of the board and it works, but I have yet to
try the electric skillet.

Don't try mounting SMD LEDs that way or you'll turn them into
Dark-Emitting Axial Diodes. Inductors are a problem, too.

Can't imagine the manufacturer even acknowledging that possibility exists.

In today's litigious society and with CA Prop whatever, I suspect
you're right.

Back in the day when I prototyped pc boards I had a hot plate, with a
good temp control setup, preheating the board is critical to dry out
the flux in the solder paste. Would then use a hot air unit to melt
the solder, it is impossible to do this on a whole board with out the
preheat to stick things down.

An electric skillet would be good to preheat, but using it to melt the
solder paste would be a waste of components and likely the pc board.

The leads would tend to delaminate caused by the epoxy sticking them
down would fail.
