Abstract
A printed circuit board (PCB) includes a first 90.degree. signal line. The first 90.degree. signal line connects a first location on a first layer of the PCB to a second location on a second layer of the PCB. The PCB includes a second 90.degree. signal line. The second 90.degree. signal line is adjacent and equal in length to the first 90.degree. signal line. The second 90.degree. signal line connects a third location on the first layer of the PCB to a fourth location on the second layer of the PCB.
