Hi all, I am looking for some recommendations on Underfill Equipment. Such as vendors, pumps, material, etc... We will be initially underfilling a 10mm x 10mm, 0.8mm pitch, 0.35mm ball uBGA on FR4 and going down in size and pitch from there. And

Guys I was wondering if anybody out there had any suggestions for cleaning populated pcbs that have been contaminated with salty sea water . There is alot of evidence of white residues and salt deposits on the pcb's. I've tried putting them through

Dear adam Sounds to me like it may not be Salt water contamination or even flux residue's, as both of these are commonly cleaned semi aqueosly or with IPA. Have you considered it may be Talcum powder used as fillers in solder resist, mineral salts

Dear Colleagues, I'm am experiencing some problems with nonwetting of primarily 0603 packages. The problem is infrequent but occures just enough for my QA dept. to notice. My reflow profile seems to be correct and the vast majority of parts solder f

Why would you get black pad from rework? I could be wrong but once the pad has accepted solder from the first reflow process wouldn't that eliminate the possibility of a latent finish defect? I am curious. We do perform rework on ENIG all of the tim
