LAYOUT METHOD OF PRINTED CONDUCTORS WITH MAGNETODIELECTRIC COATING FOR CIRCUITS WITH TRIPLE MODAL REDUNDANCY Russian patent published in 2023 - IPC H03H3/00 H04B15/02 H05K3/46 

FIELD: electrical engineering.

SUBSTANCE: design of printed circuit boards (PCB), in particular methods for their layout. The layout method includes the layout and routing of the redundant and backup circuits on the PCB with a reference conductor. The reference conductor is made in the form of two separate printed conductors inside the PCB dielectric substrate, laid one under the other parallel to each other and shorted to each other. The redundant circuit, consisting of active and passive conductors, is routed on one of the outer sides of the PCB dielectric substrate, and the redundant circuit, consisting of two passive conductors, is routed on the opposite outer side of the PCB dielectric substrate. The conductors of the redundant and backup circuits, together with the reference conductor, form a five-wire connected transmission line. In this case, radio-electronic components are placed on the outer sides of the PCB on redundant and backup circuits coated with a magnetodielectric material with a relative dielectric and magnetic permeability greater than that of the PCB substrate material.

EFFECT: reduction in the susceptibility of the redundant circuit to external conducted emissions and a decrease in the level of radiated emissions, an increase in delays and an increase in maximum attenuation.
