Abstract:
A multi-layer circuit board for use with a connector or component having pins, comprising:a plurality of conductive planes, each pair of adjacent conductive planes separated by a dielectric layer; a plurality of plated through holes, none to all of said plated through holes electrically contacting at least one of said conductive planes, those plated through holes not electrically contacting a particular conductive plane electrically isolated from and passing through a gap in that particular conductive plane; and a plurality of thermal breaks formed around each plated through hole in each conductive plane to which said plated through hole is electrically connected, said thermal breaks located between said plated through hole and a plurality of thermal vents, said thermal vents located in a pattern around each plated through hole in each conductive plane to which said plated through hole is electrically connected.
