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.

Short of placing a large hole in the center of the circuit what methods are employed to assure that circuits fail at ET.
