Abstract: A printed circuit board (PCB) may include antipads, used to provide clearance for backdrilling, which may be sized to allow backdrilling in a way that minimizes the presence of stubs. The PCB may include pads to connect a component to the PCB and vertically disposed vias connected to at least some of the pads. The PCB may further include horizontally disposed signal layers, electrically connected by the vias, to route signals from the component, received from the vias, to an edge of the component, in which signals associated with the component closer to an inner portion of the component are routed to the edge of the component on higher ones of the signal layers than signals associated with the component further from the inner portion of the component.
