Abstract:
A printed circuit board is disclosed. The printed circuit board includes a first signal transmission layer, a via and a second signal transmission layer. The via connects the first signal transmission layer to the second signal transmission layer. The via includes a first region made of a first dielectric material having a first dielectric constant, and a second region made of a second dielectric material having a second dielectric constant lower than the first dielectric constant. The via allows AC Component of an electromagnetic signal to be transmitted from the first signal transmission layer to the second signal transmission layer while blocking any DC component of the electromagnetic signal.
