Because this is so sporadic it makes me wonder if the panels displaying these problems were stripped and recoated? Panels that get stripped and recoated are often insufficiently cleaned prior to recoating, this may account for the randomness of the problem.

The laminators have been thoroughly checked out so we don't suspect them and. The problem we are seeing is what looks like a seeping under the film in copper plating. When the panels are completed the traces are somewhat irregular and not as crisp edged as normal. What is frustraing is that this happens so sporadically and may only affect a couple of panels out of a long run or all panels in a short run. Any suggestions would be greatly appreciated.
