Ah fooey....

(thumbs nose at stooge.... ;^)

I just use regular old fashioned rosin core solder... (Ersin Multicore, Kester
44 etc) The flux gets very brittle and can be flicked off with a sharp pointy
thing....

(which.. you agree J larry... you are NOT allowed to play with!)

Then I brush the residue off with a nylon brush... much like a toothbrush.

I don't like the idea of water on my components... I realize this is how many
commercial places do them these days.

I also don't like.. "no clean" because er... you don't clean them.....

Usually the flux is no problem... but for VCO, S/H especially... you NEED to
have a very very clean board of you ask for trouble

(oh...a WISE guy eh ...nyuck nyuck  !!!)

Last board I cleaned was the Chris MacDonald "Mini Modular"... just before the
polystyrene caps and pots went on  (now see... I'd never wash one of those pots
in water...).   I warmed it up with a heat gun to soften the flux... and used a
WHOLE CAN of "Ozone-Kill" on it.  You when you sun yourselves this summer under
the expanding Antarctic Hole... think of me.  I'll be in my UV protected
basement... jamming !!!  ;^)
