Eric: I�ll pass on the uV and ammonia, also. Thoughts are: 1 You�re correct that the temperature/humidity mix can be a big driver to latex peelable solder mask cure time, but don�t overlook material thickness. Dispensers put material in a very th

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.

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

Is there a peelable solder mask which can withstand an automated aqueous wash ? I need to prevent water ingress into SMT modules during the wash cycle.

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
