Mark, that would be a good report to have a look at can you post it on the site or mail it out to me? Also I've been having an issue with blue peelable solder mask on silver boards where it peels the silver off with it. I've only seen this since my v

You know you'd think that wouldn't you but the only tiem I knew the vendor had changed something was when the silver started to fall off the boards!... you can tell I wasn't chuffed Now I have to say I do prefer Dunkin's to Krispy but I can't say I'

Is the peelable mask (put on by the boardhouse) flat on the surface of the pcb? If so can you tell me the material name, so maybe I can find a picture? We have to print adhesive on the board, so the mask has to be flat. That is why Kapton from the b

Sure, I'd expect your PCB fab has given you a information sheet on handling, storage, and whatnot, including recommended temporary solder masks. The cats & kitties in the stockroom are the first people to start your search. It's probably squirreled

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

Hi, We have solder reflow use with water soluble flux and Tin/lead process. There is special glass component which needs to mask during reflow soldering and wash flux+solder mask post soldering. The existing solder mask does washes off. But leaves

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
