Abstract
Various apparatus and methods of addressing crosstalk in a circuit board are disclosed. In one aspect, a method of manufacturing is provided that includes forming a first layer of a circuit board with a first signal trace and forming a second layer of the circuit board with a second signal trace. A first guard trace is formed on the first layer and offset laterally from the first signal trace but at least partially overlapping the second signal trace and a second guard trace is formed on the second layer and offset laterally from the second signal trace but at least partially overlapping the first signal trace.
