Circuit board

A circuit board, comprising:

• a pair of first signal terminals, comprising a first terminal and a second terminal arranged in a specific direction from an edge of the circuit board, and the first terminal and the second terminal formed on a first side of the circuit board,
• a pair of second signal terminals, comprising a third terminal and a fourth terminal arranged in the specific direction, wherein a first shortest distance between the first terminal and the fourth terminal is not the same as a second shortest distance between the second terminal and the third terminal, and
• a first trace assembly, comprising:
• a first trace, formed on a first specific layer of the board circuit, extending to a second specific layer of the board circuit through one of a plurality of first vias, and returning to the first specific layer through another of the plurality of first vias so as to electrically connect to the first terminal and the third terminal, and
• a second trace, formed on the first specific layer, extending to the second specific layer through one of a plurality of second vias, and returning to the first specific layer through another of the plurality of second vias so as to electrically connect to the second terminal and the fourth terminal,
• wherein the first trace has a first length and the second trace has a second length;
• the first trace and the second trace are formed on different layers in a staggered configuration, and the first length is substantially equal to the second length.
