METHOD OF ROUTING PRINTED CONDUCTORS WITH ADDITIONAL DIELECTRIC FOR CIRCUITS WITH REDUNDANCY Russian patent published in 2016 - IPC H04B15/00 

FIELD: printing.

SUBSTANCE: invention relates to making printed circuit boards, more specifically to methods of their routing. For this purpose, the method of routing printed conductors with an additional dielectric for circuits with redundancy involves routing of reserved and backup conductors with a reference conductor in the form of a separate layer, herewith the reserved and the backup circuits have the same reference conductor, reserved and backup conductors of similar circuits are laid in pairs, parallel to each other, on the same layer, with a minimum technologically tolerable gap between the reserved and the backup conductors, along which this gap is filled with a material with relative permittivity greater than that of the printed circuit board substrate material.

EFFECT: technical result is reduction of susceptibility of the backup circuit to external conductive emissions and reduction of conductive emissions level from the backup circuit.
