Re: TO-220 Failures due to lead bending?

Roy, you are bad at insults and electronics. Study up a bit. Plenty of
conformal coatings and potting compounds out there that work with no-clean.
Done by many assembly houses everyday. Just go ahead though, you can be
wrong. Obviously, you have no clue as to how no-clean flux actually works.
If you believe it leaves a wet residue all over the board and dripping of
like snail slime, hey, so be it. You have a right to be uninformed. But
start with Humiseal, learn something.

So, I guess these tests were all lies....

I would bet the corona treaters I have designed boards for have a tad more
voltage than the toasters you tweak for a living (60kV 1020kV plus). The
noncontact printer HV modules we potted are less, but enough so that fr-4
had to have cutouts in it. They potted very well in no clean processes.

You are just dreadfully out of date and just ignorant, too, Roy.

And my sentence that got cut-off was that even some silicones have been
successfully used with no-clean, although we have not tried them here. We
have used Humiseal and other products with no coating related failures.
