We have encountered a strange problem with the plated copper over the epoxy. The peel strengths over laminate areas are better than the peel strengths over oxided copper areas. Have any of you, that are either using or are evaluating this process, encountered the same? Also we see that KMno4 attack is inconsistent. Same time temperature and concentration and processed the same way. Any information on this and how you are running in production would be helpful.
