Patent abstract

A card manufacturing technique and the resulting card are provided. The card has a ground and/or power layer extending to the edges of a circuit board for electrostatic discharge protection but also has gaps at the edge of the ground and/or power layer to avoid short circuiting with conductive segments of another layer deformed when the card is trimmed during manufacture.
