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

LONG TERM Your plans to buy a vaccuum bag resealer and a batch drying oven sound good as you say, but you�re correct. They will not help with this current situation. SHORT TERM If your connections are clean, free of pits and holes with a smooth,

We have some BGA's that don't solder very well. They weren't properly stored in regards to moisture protection. The balls look dull and rough. After reflow there seemed to be a diffinate line between the balls and the solder on the PCB's. I think

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?

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
