How many pads on the 1000 boards are affected? What is the final finish? It could be as easy as returning them to the supplier, have them remove the ink with a razor knife and recoat the boards covering any exposed copper. If they are using lead free HASL and you're using a wave solder process, and, the ink is not on the pads to a great degree it may not present any problems.

They didn't catch it in time, so now they are asking is we could accept the boards (qty = 1000) this one time. My PCB spec does not allow silkscreen on any solderable surface, so I could reject the boards, but my concern is that there may not be enough time to have more boards fabricated in time for this build. I know that the boards wouldn't be acceptable per IPC-A-610, but does anyone have any experience with this situation and the best way to handle it?
