  • polygon clerance

    Hi All,

    In the attached picture I have a differential pair surrounded by a polygon that is connected to GND net. I would like to set a clearance rule for this polygon so that It's clerance from these differential pair tracks will be 20 mill. I tried to set the clerance rule under the electrical clerance tab in the design rule however then the DRC also complains about the clerance between the tracks. So How would I create a clerance rule that would only affect the distance of the polygon from the tracks only?

    ican7 please, could you clarify - you are using Altium Designer, right? If yes, I will move the forum there.

      Do you mean should I also use the polygon cut out between the traces? Sorry I don't get what you mean Robert.
