Hello! Recently started buying PCBs with peelable mask to remove the need for Kapton tape. Had no issues with our first batch, but our supplier has over-cured the second batch - it comes off in tiny bits, and is stuck in the holes. After timing the

Hi, I am currently using a peelable mask prior to wave soldering and have started exploring water soluble/washable masks. The mask will be used with water based and alcohol based flux. Are there any compatability issues to concider and how will this

We sometimes use a peelable mask the the PCB manufacturer (board house) adds as part of their process. It may seem an expensive option but avoids: Raising P/o's for tape/peelable mask as consumables booking & inspection Booking out to the shop floo

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

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

| i had a problem here, during the wave soldering process, we apply a water soluble mask on the gold finger to protect it from contamination. But after washing, there is still some mask left on the gold finger. | Can anyone pls advise is there any pa

Hi All, I'm looking for companies who sell in-line solder mask applicators capable of dispensing peelable as well as water soluble mask formulations. Could anyone provide me with some names, please. If this is the wrong forum for this question, I d

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

You know Pat, I should just call you directly rather than post this stuff. You always have an answer. You must have been around awhile huh? :)
