Is anybody using H2O washable solder mask that comes on the PWBs you get from the fab vendor? I am researching PWB vendors that can provide this service.

Thanks.

With most folks using closed loop DI beds on their cleaners, water soluble masks have fallen out of favor. Tends to gum up the works.

Yes, thanks, I heard that, but also heard there are some formulations that are closed-loop filtration media friendly.

Probably the three biggest players for screenable, water soluble temporary soldermasks are Techspray, Chemtronics and Kester/Techform. What do they say?

Thanks Dave. I did find one PWB fab that does offer it pre-applied to the boards, Saturn PCB. I'm told the formula is proprietary but is WS. Not sure if its CL friendly though.

Our supplier told me that TechSpray does no longer manufacture their water soluble mask. I dont know is that truth or not...
