This would creates burrs and result in the PCB surfaces being scratched in all subsequent processes when the circuit boards are laid on top of one another. ![]() Generally, a sufficient distance, taking into account all the tolerances, is required to avoid milling off copper. The minimum distance between the conductive pattern/copper and outer PCB edge depends on the contour machining technology used.
