The process is a bit like a manual solder wave.. the dross is
skimmed and the board is dipped in flux and sort of rotated
as it touches the pot surface and sizzles away.

What I've seen is leads cut to maybe 1/4" +/- and trimmed afterwards
with a special horizontal carbide slitting saw. This has the
potential to fracture the joints, particularly on a cheap single
sided board. I'm afraid this process is not going to be NASA
qualified any time soon.. but it might be good enough if your board
is low density and quality is not a big concern (but cost is).
