RADIO-ELECTRONIC BLOCK AND METHOD OF ITS MANUFACTURING Russian patent published in 2009 - IPC H05K1/00 H05K5/06 H05K7/14 

FIELD: physics; radio.

SUBSTANCE: of invention concerns field of radio electronics and can be used at manufacturing of radio-electronic blocks of package type. It is reached because the radio-electronic block contains the case consisting of metal frameworks, elastic sealing interleafs and two walls joined in a package, and also printing assemblies with the demountable connectors, anchored on the mentioned frameworks. The covering and covered stage claws are contained accordingly at end faces of frameworks on their exterior and interior contours, and the height of covering stage claws is less than height of the covered ones, and elastic sealing interleafs are located between end faces of frameworks and the covering stage claws and executed from hermetic. The method of manufacturing of the radio-electronic block includes manufacturing of printing assemblies, their fastening on metal frameworks, arrangement of elastic sealing interleafs at the end faces of frameworks, the makingup of frameworks with two walls in a package and tightening of the package by screws, thus elastic sealing interleafs are disposed after tightening of a package by filling of backlashes with hermetic between end faces of frameworks and covering stage claws.

EFFECT: increase of radio-electronic block reliability.
