Patent ID: 7036710

Claim:
A method for implementing an impedance-controlled coupled noise suppressor for a differential interface solder column array comprising the steps of: providing an impedance-controlled coupled noise suppressor structure having a plurality of elongated through openings arranged in a predefined pattern with one or more of the through openings receiving a differential signal pair of solder columns; said elongated through openings having electrically conductive sidewalls and being electrically connected together; said predefined pattern of the elongated, electrically conductive through openings corresponding to a layout of solder columns; inserting said solder columns through the elongated through openings of the impedance-controlled coupled noise suppressor structure, spaced apart from the electrically conductive sidewalls with said solder columns being attached at one end to one of the substrate or the circuit card; attaching said solder columns at another end to the other one of the substrate or the circuit card; providing an electrical connection between said impedance-controlled coupled noise suppressor structure and an image return current path of the circuit card; providing an electrical connection between said impedance-controlled coupled noise suppressor structure and a return current path of the substrate; and wherein the steps of providing an electrical connection includes the steps of providing a solder connection.
