Good Day Everyone, I have a BGA rework that has some chipped/damaged solder mask that will need to be repaired prior to BGA replacement. I was wondering what materials are being used in the industry for this type of application. Any help would be g

I guess i might want to throw this in for future reference. After speaking with our board supplier he states that this mask is fully cured when it reaches approximately 180C. I beleive this since we usually probe the repaired area after putting the

I have been reballing some BGA's. Some of the BGA's have solder mask damage and cannot be recovered until I find a way to reapply the solder mask. Are there any suggestions?

PCB BOARD - After removal of the BGA from the PCBA. In the midst of removal of the solder at the PCB, the green mask was scratched. If we do not repair the green mask, the whole board will have to be scrapped. Which repair kit do you recommend. W

Hello Mark, It is possible that SolderMask, Inc. could selectively remove the existing solder mask, clean and reapply a Photoimageable solder mask to the BGA area. Mostly likely the mask on your boards is a Liquid Photoimageable Solder Mask (LPIS

Hello Mark, To date all solder mask rework we have done has been on the PCB board. I believe that it possible to reapply solder mask on to the ball side of the BGA. Would it possible to evaluate some of your BGA's? You can contact me at 714 842

You're not sposed to pull the mask from the BGA when reworking it!!!! ;-) Well, if you insist. You can be as fancy as you want. Basically, all you need to do form a dam to prevent the solder from flowing from the pad to the via and starving the

I'm looking for some input on a pay scale for experienced SRT/DRS operators. They do not do any profiling or process work - only remove/site prep/replace type work, along with any 'special' jobs like trace repair, masking repair, etc. They're current

Hi, thank you both for answering. Unfortunately, due to volume and the components we repair it is not viable to switch to selective soldering. I already contacted TechSpray and they suggested that I switch to 2211, but I don't think it's going to ho
