Gary,
     Are you looking for PWB fabrication process points or PWA assembly?
     Looking at PWA assembly criteria, One thing you need to keep in mind 
     is that, more copper means more heath sinking at soldering so you need 
     to pay attention to the connections and implement proper thermal 
     relief patterns.

Would like input on the subject of 1 oz. vs. 2 oz copper thickness on inner 
layers. What types of end products would be affected if 1 oz. were 
substituted for 2 oz? What design considerations are most critical? Is it 
safe to say that 1 oz. vs. 2 oz. should no longer be an issue? 
Thank you for input.
