Claim:
1. A structure for attaching a coaxial or a micro coaxial cable to an interior a side of an exterior pad of a printed circuit board to improve signal integrity for an electrical circuit, comprising: a one layer or else a two or more layer printed circuit board (PCB) having a formed opening having an entry side therein in which either a coaxial or micro coaxial cable is placed through the formed opening of the PCB so that a center conductor of said cable extends to or near an outer conductor layer of said exterior pad of the PCB where the entry side of said opening is located, said coaxial cable having an outer shielding and said outer shielding is free from any encasement within said opening other than said opening to reduce an effect of cross talk and ground shielding is attached to via plating to bottom of a pad below said PCB; and said center conductor extends vertically upright to attach and is either attached to an interior side of said exterior pad of the PCB on a side where said entry side is located or has a pressure or friction contact to a corresponding metal on the PCB to provide a ground connection or signal connection for relying on its electrical contact.
