Dave,
     
     We simply use a hand-held number stamp, 3/8", and a hammer to identify 
     the discrepant circuit. The number correlates to a defect code for 
     accurate reporting. We did have some escapes when using 3/16" or 1/4" 
     stamps and went to a program that entailed drilling a 1/4" hole 
     through the circuit right on the NC mach. This ended up being too much 
     trouble at photo-develop and PISM and we went to a larger stamp, 
     bigger hammer and making numerous marks on the circuit.

     I am looking for any input that other board manufacturers may have on 
     handling x-outs of a single circuit at Drill on multiple-up panels.  
     Short of placing a large hole in the center of the circuit what methods 
     are employed to assure that circuits fail at ET.
     
     Please forward any suggestions/methods to:
