RADIO-ELECTRONIC BLOCK WITH INTRAPLATE SCREENING Russian patent published in 2009 - IPC H05K1/00 H05K9/00 

FIELD: physics, radio.

SUBSTANCE: invention concerns radio engineering and can be used at designing of radio-electronic blocks. Radio-electronic block with the intraplate screening, containing the structural printed-circuit board with the outside and interior conductor layers, bearing printing conductors and the electroradioelements grouped on screened by means of barrier and plane screens to the functional bands, and barrier screens are formed by the joined corresponding constructive devices of interlaminar linkings by the screening printing conductors executed in outside and interior conductor layers the friend under the friend with disruptures for printing conductors, traversing barrier screens, and plane screens are formed by the earthen planes serving by conductors of potential "ground" feeding for electroradioelements of screened functional bands, thus specified earthen planes located in one interior conductor layer are joined among themselves by earthen crosspieces and connected to a point of an application of potential "ground" on the structural printed-circuit board, And each screened functional band has the natural barrier screen located on its perimeter, and the natural earthen plane serving by its plane screen, located in a band sweepped by the barrier screen, thus earthen planes and barrier screens in screened functional bands structurally are not related with each other, and constructive devices of interlaminar linkings and devices of the barrier screen are executed in the form of the metallised groove of the interlaminar linkings transiting along a printing screening barrier with printed-circuit boards erected in it, electrically by uniters the adjacent plates and-or uniters the adjacent payments with a payment with an intraplate screening where one leg of the metallised groove concerns one screened band, and other leg of the metallised groove - to other screened band, Thus the place of transition to other leg of the metallised groove is isolated from one leg of the metallised groove on a thickness of the plate, between two screening bands in places of transition barrier screens are isolated from one leg of the metallised groove to other leg also, and barrier screens are related to a point of an application "ground" each one with an own wire with the argentiferous coat, transiting through a ferrite ring.

EFFECT: increase of efficiency of protection of the radio-electronic block from action of electromagnetic noises, decrease of its mass and dimensions parameters, simplification of manufacturing techniques and maintenance of high reproducibility of the radio-electronic block.
