Abstract:
1. A circuitized substrate comprising: a first conductive layer having a first plurality of conductive pads oriented in a pattern and adapted for being electrically coupled to a first electrical component; a second conductive layer including a plurality of signal lines, selected ones of said signal lines being electrically coupled to respective ones of said conductive pads of said first plurality of conductive pads; a first dielectric layer positioned substantially between said first and second conductive layers, a third conductive layer including first and second voltage planes oriented adjacent one another and a second plurality of conductive pads also oriented in a pattern, selected ones of said second plurality of conductive pads being electrically coupled to respective ones of said signal lines of said second conductive layer, said second voltage plane having a different voltage than said first voltage plane; and a second dielectric layer positioned substantially between said plurality of signal lines of said second conductive layer and said third conductive layer, said plurality of signal lines of said second conductive layer being positioned substantially between said first conductive layer and said first voltage plane of said third conductive layer but not being positioned between said first conductive layer and said second voltage plane oriented adjacent said first voltage plane so as to extend between said first and second voltage planes, thereby substantially preventing impedance disruption during the transmission of signals through said signal lines.
