RADIO ELECTRONIC UNIT WITH INTRABOARD SCREENING Russian patent published in 2001 - IPC

Abstract RU 2172082 C1

FIELD: radio electronics. SUBSTANCE: radio electronic unit includes multilayer printed circuit board carrying printed conductors, lands and electric radio elements forming functional zones. Supply conductor of GROUND potential located in i-th inner conducting layer of printed circuit board of screened zone is manufactured in the form of metallized plane. Screened zone of at least outer conducting layer of printed circuit board is surrounded over perimeter by printed screening barrier coupled with the use of metallized holes of interlayer connection to additional metallized plane located in specified j-th inner conducting layer of printed circuit board, where j>i counting from outer conducting layer with printed screening barrier. Metallized plane, printed screening barrier and holes on interlayer connection coupling them form current conducting framework of intraboard volumetric screen inside which printed conductors of screened zone are located , supply conductor of GROUND potential included. EFFECT: realization of local screening. 1 cl, 9 dwg
