Abstract
A method and an apparatus for connecting a coaxial (or a micro coaxial) cable to the bottom side of a printed circuit board (PCB) in order to improve signal integrity of a test circuit. A coaxial or a micro coaxial cable is directly connected to a coaxial cable to the bottom sides of pads located on an exterior later of the PCB.
Claims28
A method of attaching a coaxial or a micro coaxial cable to a side of a pad of a printed circuit board to improve signal integrity for an electrical circuit, the steps comprising:
- forming an opening having an entry side in either one layer or a two or more layer printed circuit board (PCB);
- placing either a coaxial or micro coaxial cable through the formed opening of the PCB so that a center conductor of said cable extends to or near said pad of the PCB on a side of said pad where the entry side of said opening is located, said coaxial cable having an outer shielding;
- and
- either attaching the center conductor to said side of said pad where said entry side is located of the PCB or relying upon a pressure or friction contact to corresponding metal on the PCB to provide a ground connection or signal connection for relying on its electrical contact.

A structure for attaching a coaxial or a micro coaxial cable to a side of a 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 said pad of the PCB where the entry side of said opening is located, said coaxial cable having an outer shielding;
- and
- said center conductor is either attached to a side of said 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.
