Conductive track arrangement on a printed circuit board

A printed circuit board includes conductive tracks that alternate between two layers and repeatedly cross one another in a manner to simulate conventional twisted wirings. The tracks are formed by interconnecting individual segments 1, 1' formed on the two layers by vias 3. The layers may be provided with conductive areas to provide shielding, and further shielding layers may also be added. The resulting PCB may be of a large-scale type that can be used to replace conventional twisted and shielding wiring.
