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: David A Wettstone Hadco Corporation Derry, NH Tel: (603) 432-2210, ext. 3584 E-mail: [log in to unmask]
