Subject: Oilly stuff after lamination

Hi,
We sometimes find some oilly stuff left on the Cu foil (especially near the 
multiline hole area ) after lamination which we suspect coming from silicone 
rubber press pad or the tadler release sheet we used.  It is very difficult 
to remove and is hurting the yield.  We would appreciate anyone who can help 
us solving this issue (espacially how to avoid it).
