Abstract

In the circuit board (5) proposed, two signal layers are disposed between two screening layers (6). The two conductor tracks (1 and 2) of a symmetrical pair of conductors are divided between the two signal levels. Two adjacent conductor pairs are associated with each other in such a way that their connection planes cross.
