Hi, Gusti,

If it's just an acrylic conformal coating, one of its useful features is
that you can solder through it, clean of the flux residues and locally
repair the coating afterwards. Humiseal provide some literature and
application notes that may help you.

              Subject: [TN] Solder through conformal coating








Hi TechNet $B!G (Bs,
I am in the situation to reduce time consuming with masking and de-masking
a couple of pads for an assembly covered with an acrylic lacquer. I am
asking if someone have tried to solder by hand a component (with gull-wing
terminals) without remove the conformal coating. I have experimented and
observed that it can be done. It is a silly question or not?
Any reaction will be welcomed.
Gusti
