I'm not sure what boards or process your using, but there may not be
a need to coat the board if your using the positive resist boards.

I haven't tried this, but Read at MG's site:
http://www.mgchemicals.com/techsupport/photo_inst.html

"Removal of resist is not necessary when soldering components to
your board. By leaving the resist on, your circuit is protected from
oxidation. Tin plating your board is not necessary. When soldering,
the heat disintegrates the resist underneath the solder resulting in
an excellent bond."

I am using the $3.99 6" x 3" boards by GC currently, but I will try
next time to leave the resist on and solder through it. Then just
using a flux cleaner to remove the solder flux, I suspect the final
product might be very nice ;-)

Does anyone have a any home-brew flux remover formula?
I need to know what will clean a board of rosin flux easily/cheaply.
I am always looking for home-brewed concoctions as opposed to
aerosol cans!
