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.
Dan

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:
