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

Yes, we have had this happen with certain solder masks over the years. Hot air gun is the best solution we can find if the oven doesn't do it. Back in the day when we had a vapor degreasor, freon based solvents would also remove the clouding. Let

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

Just out of curiosity - what is the rationale behind specifying mask thicknes?

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

Hi, i'm facing solder mask peel off but limited to the solder defined pad only(opening area). no peel off on the other area and it happened on electroless nickel immersion gold finishing only. for other finishing is not affected. kindly advise if you

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
