RADIO-ELECTRONIC BLOCK AND METHOD FOR MANUFACTURING IT Russian patent published in 2008 - IPC H05K7/00 H05K7/20 

FIELD: radio-electronics, possible use in blocks of radio-electronic equipment, where large number of surface mounting elements is used, and in devices with high density of inter-board connections.

SUBSTANCE: radio-electronic block contains a set of flat parallel boards, which are mechanically interconnected to form a packet and electrically connected along engagement plane by means of detachable connectors, consisting of contact-parts in form of rods and sockets. Both boards themselves and the body of radio-electronic block act as body of electric connector, ventilation windows are present. Radio-electronic block is manufactured according to method, which includes setting up flat parallel boards, mechanically interconnecting aforementioned boards to form a packet with ensured electric connections between them along their engagement plane by means of detachable connectors. Connection of walls of radio-electronic block and the set of boards is realized by means of at least one heat-draining pipe with possible thermal contact for heat-loaded elements.

EFFECT: increased reliability, ensured more dense placement of electronic boards in a packet, reduced length of inter-board electric connections, creation of single board packet grounding contour with the body of radio-electronic block, increased efficiency of radio-element cooling, reduced mass and size characteristics, simplified construction and radio-electronic block manufacturing technology.
