Ground Relief Cut-outs

6. Avoid routing traces near irregularities in the reference ground planes. Irregularities include cuts in

the ground plane or ground plane clearances associated with power and signal vias and through-hole

component leads.

7. Provide symmetrically located ground tie stitching vias adjacent to any high-speed signal at an appropriate

spacing as determined by the maximum frequency the trace transports (λ/4). See Figure 9-22 as an

example.

8. When high-speed signals must transition to another layer using vias, transition as far through the board as

possible (top to bottom is best case) to minimize via stubs on top or bottom of the vias. If layer selection is

not flexible, use back-drilled or buried, blind vias to eliminate stubs. Always place two ground vias (“return

vias”) close to critical high-speed signal trace via when transitioning between layers to provide a nearby

ground return path. See Figure 9-25 and Figure 9-26 as examples.
