ABSTRACT:
A multi-conducting through hole structure is provided. The multi-conducting through hole structure has a substrate, at least two signal lines and at least a reference line. The substrate has a through hole passing therethrough. The signal lines are disposed on a portion of an inner surface of the through hole and extended through the through hole. The reference line is disposed on a portion of the inner surface of the through hole and extended through the through hole, wherein the reference line is disposed between the lines for signal. Because the signal lines are separated by the reference line, the electromagnetic coupling generated by signals can be reduced to lower the cross-talk interference between signals passing through the through hole, so as to promote the signal-transmission quality.
