Abstract:
A printed circuit board (PCB) includes a differential pair having a first differential trace and a second differential trace, a first via having an upper cap and a lower cap, and a second via having an upper cap and a lower cap. The first differential trace includes a first segment and a second segment, the second differential trace includes a third segment and a fourth segment. The first and the third segments are electrically coupled to the upper caps of the first and the second vias respectively. The second and the fourth segments are electrically coupled to the lower caps of the first and the second vias respectively. The first and the third segments extend from corresponding upper caps in different directions, the second and the fourth segments extend from corresponding lower caps in different directions.
