I am having cleaning problems when processing PCB's which have TAIYO solder mask on them. After processing, hand soldering and cleaning, a sticky residue is remains, resulting in a cosmetically poor finish with tide marks etc. Other soldermasks do no

Does anybody know how to remove solder mask from pads that were masked over.

Am looking for a dispensable water soluble solder mask or peelable solder mask that can be dispensed and be run through a reflow oven with no swelling or degradation. Any leads on any materials or manufacturers to contact?

Thanks Tim. Additional thoughts are: * We've talked here on SMTnet about hole fill previously. * That your ability to get hole fill is probably limited by mask in the hole makes us very uneasy, because hole could have varying levels of solder mask i

Excessive mask thickness also can wreak havoc on stencil printing.

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

Carol, I think the guys are right about you stand off problem but I want to address the wrinkleing of your masking. Although I think the temps you are subjecting the board to are very high and more than likely creating problems of their own. I th

I'm looking to mix up a batch of purple solder mask. Has anyone found a good ratio of red and blue that produces a pleasing purple? 50/50 produces a pretty ugly grape color. Is there a standard ratio most fabs use?
