Differential trace pair system

An information handling system (IHS), comprising:

• a processor;
• a circuit board having a connection pad array that couples the processor to the circuit board, wherein the connection pad array includes a first connection pad and a second connection pad that is spaced apart from the second connection pad;
• and
• a differential trace pair that is provided in the circuit board and that includes a first differential trace pair portion located outside the connection pad array and having a first width, and a second differential trace pair portion extending through the connection pad array and having a second width that is smaller than the first width, wherein the second differential trace pair portion includes:
• a first outer edge and a second outer edge that is located opposite the second differential trace pair portion from the first outer edge, wherein the first outer edge and the second outer edge define the second width;
• a first connection pad channel defined by the first outer edge adjacent the first connection pad;
• and
• a second connection pad channel defined by the second outer edge adjacent the second connection pad, wherein the first connection pad channel and the second connection pad channel provide a third width of the second differential trace pair portion that is smaller than the second width.

A method for providing a differential trace pair, comprising:

• providing a board including a board structure having a first board structure member and a second board structure member that is spaced part from the first board structure member;
• creating a first differential trace pair portion of a differential trace pair in the board and outside the board structure, wherein the first differential trace pair portion includes a first width;
• creating a second differential trace pair portion of the differential trace pair in the board that extends from the first differential trace pair portion and through the board structure, wherein the second differential trace pair portion includes a first outer edge and a second outer edge that is located opposite the second differential trace pair portion from the first outer edge, and wherein the first outer edge and the second outer edge define a second width of the second differential trace pair portion that is different than the first width;
• defining a first board structure member channel in the first outer edge adjacent the first board structure member;
• and
• defining a second board structure member channel in the second outer edge adjacent the second board structure member, wherein the first board structure member channel and the second board structure member channel provide a third width of the second differential trace pair portion that is smaller than the second width.
