Hello all THE PLANES SHOULD BE PULLED BACK AT LEAST .025 FROM THE BOARD EDGE. WHAT I HAVE DONE IS PULL THE PLANE BACK .025 FROM THE INSIDE AND OUTSIDE OF THE BOARD EDGE. THIS WAY YOU ARE NOT ROUTING THROUGH COPPER OR EXPOSING COPPER ON THE BOARD EDGE. EXPOSED COPPER AT THE FINGER EDGE OF THE BOARD IS REJECT. THERE IS A WAY YOU CAN REWORK. GIVE ME A CALL. William W.

What specification provides criteria for power-ground planes being exposed due the bevel process, or actually exposed planes for any reason?
