I have received these awful circuit boards from a vendor that show lots of solder mask mis-registration and flaws. We used a bunch of them before we found the problem. Now we need to implement some incoming inspection. I am working on a checklist of things to check, so far it has 1 item "check solder mask registration". What else would I look for?
Also considering using a lab to do this on a sample basis, does anyone have any suggestions where?
thanks,
