发明名称 Eine Vorrichtung und ein Verfahren zum Verbessern der Signalebenenübergänge bei gedruckten Schaltkarten
摘要 A method and apparatus for improving printed circuit board signal layer transitions are described. In one embodiment, the method includes the formation of a first via within a printed circuit board (PCB). A second via is formed concurrently within the PCB. In one embodiment, the second via is positioned proximate the first via to enable electromagnetic coupling between the first and second vias. Following formation of the second via, the first and second vias are connected to provide a series connection between the first and second vias. In one embodiment, the series connection between the first and second vias reduces a stub length with respect to the first via to reduce and potentially eliminate stub resonance for, for example, short signal layer transitions. Other embodiments are described and claimed.
