Hi All,
     The double treat inner layer material we use often arrives with surface
scratches - deep enough to be seen, but not deep enough to affect the
underlying copper.  These scratches are visible on the finished boards.  Is
this a cosmetic defect, or worse?  Is board performance affected?  Should
our vendor be slipsheeting this material?  Which essential question have I
forgotten to ask?

Thanks in Advance,
Mark Hargreaves
