Tin/Lead we have had no problem in masking off areas on a pcb during wave soldering. Lead Free alloys, Nickel Silver Copper would there be any compatability issues with a Peelable latex solder mask containing Ammonia. Really hot need to know.

Ammonia in Peelable solder mask compatability to lead free

Electronics Forum | Wed Jun 22 15:03:12 EDT 2005 | patrickbruneel

The only thing ammonia can do is tarnish copper and make it more difficult to solder. And the higher temp in lead-free will discolor the latex (giving it a sticky surface), but the functionality of the mask will be intact. There should be greater co

You can use a peelable, rather than a water washable, temporary solder mask? Points are: * Vinyl peelable is preferred over latex, because of lower residues. You should be very concerned about this since you are probably running a low residue proce

If you are not washing and want to stay with a peelable mask the two basic types are vinyl and latex. Although we've seen some silicone and urethanes, they cost more. * Do not use latex peelable solder mask with a low residue soldeing process withou
