METHOD FOR REMOTE LAYOUT OF PRINTED CONDUCTORS OF CIRCUITS WITH THREE-TIME MODAL RESERVATION Russian patent published in 2023 - IPC H04B15/02 H05K3/00 H05K3/46 

FIELD: printed circuit board conductors.

SUBSTANCE: invention relates to the layout of printed circuit board (PCB) conductors. The objective of this invention is achieved by the fact that the method includes the layout of the printed conductors of the redundant and backup circuits on the PCB with a reference conductor made in the form of two separate printed conductors inside the dielectric substrate of the PCB, laid one under the other parallel to each other and connected to each other. The redundant and one redundant circuit are routed on one of the outer sides of the PCB substrate, and two redundant circuits are routed on the opposite side. Above the redundant and reserve conductors of the same circuits, the conductors connecting them are located so that they have an electromagnetic connection with them providing a modal decomposition and are connected at the ends to the reference conductor.

EFFECT: improved reliability while maintaining noise immunity due to modal expansion and due to physical protection by connecting conductors of the redundant and reserve conductors of the same circuits from the risk of mechanical damage, as well as due to the pairwise removal of the redundant and reserve conductors of the same circuits from each other, eliminating the risk of simultaneous damage to all conductors.
