One embodiment of the invention comprises an improved method for making a via structure for use in a printed circuit board (PCB). The via allows for the passage of a signal from one signal plane to another in the (PCB), and in so doing transgresses the power and ground planes between the signal plane. To minimize EM disturbance between the power and ground planes, signal loss due to signal return current, and via-to-via coupling, the via is shielded within two concentric cylinders, each coupled to one of the power and ground planes.
