Claim of US Patent No. 10,485,096
1. A differential trace pair system, comprising:a board including a board structure having a first board structure member, a second board structure member, a third board structure member, and a fourth board structure member; and
a differential trace pair that is provided in the board and that includes:
a first differential trace included on the board and extending between the first board structure member and the third board structure member;
a second differential trace included on the board and extending between the second board structure member and the fourth board structure member; and
a serpentine region of the differential trace pair that includes:
a first portion and a second portion in which:
the first differential trace and the second differential trace each have a first width;
the first differential trace and the second differential trace are substantially parallel; and
the first differential trace and the second differential trace are spaced apart by a first differential trace pair spacing; and
a third portion that is located between and electrically coupled to the first portion and the second portion and in which;
the second differential trace includes a second width that is greater than both the first width and a third width of a first differential trace section of the first differential trace that is included in the third portion and that has substantially the same length as a second differential trace section of the second differential trace that has the second width;
the first differential trace and the second differential trace are substantially parallel; and
the first differential trace and the second differential trace are spaced apart by a second differential trace pair spacing that is greater than the first differential trace pair spacing.
