| Exposed Via to Exposed Copper (Exposure) | Reports the distance between the edge of the exposed copper of an uncapped via and the exposed copper on the outer signal layers only, when closer than pp_e_spacing. Does not report spacing between pads of the same net that are fully embedded in copper. Classified by process. The reported exposed via and exposed copper surface do not touch. |
