Well hello again Dave,

Hmmm... specific implementations aside temporarily, I've got apparently=20
similar usage questions as the original poster of this thread.  Tell me i=
f=20
this is the correctly assumed process ... melt solder in pot, brush flux =
on=20
PCB bottom, populate components, clip leads, dip board in for a few secon=
ds,=20
then remove flux... ?
Sounds difficult to just get the bottom of the PCB wet with solder -- doe=
sn't=20
that pose a problem if solder gets on the top?  And I'm sure all componen=
ts=20
can't be dunked in, so some must be done later, but wouldn't the solder b=
ath=20
plug up the holes?

The dross stick seems logical to skim off the oxidation from the top.=20

Now if you can do this in a frying pan, what sort of temps do you use?

BTW, 5 seconds sounds like a long time.  I would imagine 2-3 seconds bein=
g=20
quite enough.

If you need a wave, perhaps you could modify one of these...

:-)

Alternately, perhaps all you need is some sort of very simple lever devic=
e,=20
which crosses over the pot and has clips to hold the board about midway. =
 The=20
long end of the lever would give you more precise control over how much t=
he=20
board is lowered.

Cheers,
-Neil.
