METHOD FOR ROUTING A DOUBLE-SIDED PCB WITH MODAL RESERVATION AND A REDUCED NUMBER OF CONDUCTORS Russian patent published in 2022 - IPC H05K3/00 H04B15/02 

FIELD: printed circuit boards.

SUBSTANCE: invention relates to the design of printed circuit boards, specifically to methods for tracing them. The effect is ensured by the fact that in the method for tracing a double-sided printed circuit board that protects against ultrashort pulses, including the layout and routing of the redundant and backup circuits, so that the layout and routing of the redundant circuit is performed on the upper layer of the substrate, and the layout and routing of the backup circuit is performed on the lower layer the substrates are mirrored to the top layer, so that the redundant and redundant conductors are located one under the other. On the top layer of the substrate, the reference conductor is made to the left of the redundant conductor, and on the bottom layer of the substrate, the reference conductor is made to the right of the reserve conductor. In this case, the value of the line length, multiplied by the value of the difference between the maximum linear delay and the largest of the remaining linear delays, is not less than the sum of the durations of the front of the flat top and the decay of the ultrashort pulse supplied between the reserved and reference conductors.

EFFECT: reducing the weight of the circuit board without reducing the suppression of the ultra-short pulse.
