PRINTED CIRCUIT BOARDS WITH RESERVE CIRCUITS ARRANGEMENT METHOD Russian patent published in 2017 - IPC H04B15/02 H03H3/00 H05K3/36 

FIELD: printing industry.

SUBSTANCE: in the PCB layout method, which includes the mutual arrangement of the redundant and standby cards, the layout and tracing of the redundant and standby boards, the reference conductor is made as separate layers on the redundant and standby cards. Reserved and reserve boards glued layer dielectric with relative dielectric permeability greater than dielectric substrates and reserved. The route that correspond to each other redundant and backup chains are parallel to and below each other in glue layer of dielectric, reserved and reserve electronic components are placed on bonded parties reserved and backup gluing layer PCB dielectric. In case of failure of the reserved circuit, the same technical result will be achieved in the backup circuit.

EFFECT: reduction of reserve circuit sensitivity to external conductive emissions and reduction of the conducted emissions level from the reserved circuit.
