Printed Circuit Design Tutorial (B. Tab-routing)

    B. Tab-routing

    When the board has irregular shape, or the board need a clear edge then the panel need be tab-routed. Fig 8 shows a drawing for the tab -routing panel, Fig 9 is the photo of the tab-routing panel. In the tab-routing panel in order to break the board off the panel after assembly, V score or "mouse bite holes" can be used. Mouse bite holes is a line of holes works the same way as holes on array of stamps . But keep in mind V score will give a clear edge after the boards are break away from the panels, "mouse bite holes" will not give a clear edge.
