I would appreciate anyone's help regarding problems with poor 
adhesion of Dupont 9400 series resist.  This film is prone to 
break down in our copper and tin tanks, and also in Body Plate 
Gold (most prevalent.)  We have tried a variety of process changes 
including increasing the laminating roll temp. to 120 degrees C.
but have not solved this problem.



Thanks all!
