METHOD OF SYMMETRIC ROUTING OF SIGNAL AND REFERENCE CONDUCTORS OF CIRCUITS WITH MODAL RESERVATION Russian patent published in 2023 - IPC H05K1/02 H04B15/00 

FIELD: printed circuit boards.

SUBSTANCE: according to the method of tracing printed circuit conductors of circuits with redundancy, including the tracing of redundant and reserve conductors with a single reference conductor, in which the redundant and reserve conductors of the same circuits are laid in pairs, parallel to each other, on one side, with the minimum technologically acceptable gap between them, a single reference conductor is made in the form of conductors on the other side of the printed circuit board, whereas the ends of each reference conductor are located under the outer ends of the corresponding redundant and reserve conductors.

EFFECT: reduced bending of the printed circuit board, the mass of the end device, the susceptibility of circuits to external conductive emissions and the level of conductive emissions from them.
