Abstract
A printed circuit board, and a method of fabricating the printed circuit board is disclosed. The printed circuit board includes at least one coaxial via. A hollow via is disposed in the printed circuit board. A metal sleeve is formed around the circumference of said hollow via. An inner conductive path is disposed in the hollow via. Additionally, an insulating material is disposed in the hollow via, between the conducting path and the metal sleeve. The conductive path is used to connect signal traces disposed on two different layers of the printed circuit board. In some embodiments, these signal traces carry signals having a frequency above 1 GHz, although the disclosure is not limited to this embodiment.
