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 the current Panasonic / KME bulk feeder design use the indexing concept developed by Taiyo Yuden (Japan), or is it based on the Nitto (pneumatic) concept?

thanks Dave, solder mask use is AUS 5 from Taiyo ink, solderability of the contam area is still pass the min spec. gold thickness is ~ 1 um and Ni layer is ~10um. can solder mask bleed cause contam? forget to tell the product is full body gold (FBG)

Hi Dave, I haven't tried the Probimer yet, but the Taiyo ink didn't hold up too well. As a PCB fabricator, finding a white soldermask that has good trace coverage and survives 4X solder immersion (HASL) is like the holy grail of white soldermask.

Hello Netters, I need some info, Earl or Dave, I have a PCB that exhibits a white layer on solder side. It does not appear to be surface residues (IPA has no effect), but looks like its under solder mask. My first guess is that the LPI solder mask
