METHOD FOR REMOTE TRACING OF PRINTED CIRCUIT CONDUCTORS WITH SINGLE MODAL REDUNDANCY Russian patent published in 2023 - IPC H04B15/02 H05K3/00 H05K3/46 

FIELD: printed circuit boards.

SUBSTANCE: method for tracing printed circuit conductors with redundancy includes tracing reserve and redundant conductors with a single bearing conductor. The redundant and reserve conductors of the same circuits are laid in pairs, parallel to each other, on one side. Above the reserve and redundant conductors of the same circuits, a conductor connecting them is located so that it has an electromagnetic connection providing modal decomposition with these conductors and is connected at the ends to the bearing conductor.

EFFECT: increased reliability while maintaining interference immunity by modal decomposition due to physical protection by the connecting conductor of the reserve and redundant conductors of the same circuits against the danger of mechanical damage and by moving the reserve and redundant conductors of the same circuits away from each other, eliminating the risk of simultaneous damage to both the conductors.
