     Can anybody tell me what is an effective pressure setting to minimize 
     the puddling effect that occur at the center of a panel during 
     etching?
     
     It is often the case that the line width at middile part of an etched 
     panel is 0.5 to 1 mil wider than the line width at the edges for 1 oz 
     cladding. Anybody have any comment on this?
