1. A circuit board having at least one peripheral edge comprising:

  • a first conductive layer having conductive segments at the edge of the circuit board;

    a first insulative layer;

    a second conductive layer separated from the first conductive layer by the first insulative layer, positioned below the first conductive layer, and extending to the edge of the circuit board, the second conductive layer having gaps at the edge of the circuit board, one or more of the gaps aligned with the conductive segments whereby any deformation of the conductive segments that extends over the edge to the plane of the second layer extends within the gaps and does not contact the second conductive layer.
