JoAnn, 1mm (0.040") gap from the board edge to conductor path/pad is typical requirement for multilayer pcb's. For one or double sided boards, you can get away using 0.5mm gap without undue mechanical stress to copper layers during scoring or routing of boards. This min. gap is recommended to allow some tolerances during board fabrication and to prevent internal layer mechanical fatigue from routing/scoring. Please check IPC-D-275, section 5.3.1.4. regards Matthew Park Automation engineer Norsat International Inc.

I personally feel that's waaaaay too much real estate to throw away but it wasn't my decision. Anyone care to help me get this changed? All help is appreciated. Happy Holidays! *<():-)> JoAnn L.
