ABSTRACT:
A printed circuit board and video switcher board containing the circuit board including a first dielectric lamina having opposed surfaces and a first layer deposited on one of the surfaces which has of a plurality of first layer signal lines on one of the surfaces. A plurality of first ground areas of defined width are arranged between the first layer signal lines such that each of the first layer signal lines has one of the first ground areas on a side thereof so that none of the first layer signal lines is immediately adjacent to another first layer signal line. A second substantially uninterrupted layer on the other surface of the first lamina forming a second ground area which is substantially coextensive with the other surface. At least two holes extend through the first lamina between the first and second ground areas and each of the holes has openings at the first ground areas and at the second ground area. A conductive member in the holes electrically connects the first and second ground areas for shielding the first layer signal lines from each other, and the separation between the holes is less than the width of the first ground areas.
