Abstract:
1. A printed circuit board comprising: an insulative substrate; a grounding layer coated upon the substrate and defining empty areas; a plurality of conductive traces formed upon an exterior surface of the printed circuit board and defining corresponding soldering portions thereof, respectively; and a dielectric fence layer disposed between the grounding layer and the conductive traces in a vertical direction perpendicular to said printed circuit board; wherein the empty areas are aligned with the corresponding soldering portions in the vertical direction, respectively; wherein each of said conductive traces defines two opposite soldering portions in a front-to-back direction perpendicular to said vertical direction; wherein said empty areas are unified together to form two through slots each extending along a transverse direction perpendicular to said vertical direction and said front-to-back direction; wherein a dimension of each of the through slot in the transverse direction is compliant with a corresponding region in which the soldering portions span in the transverse direction.
