METHOD OF SPATIAL MINI MODULE MANUFACTURING FOR RADIO ELECTRONIC DEVICES Russian patent published in 2008 - IPC H01L25/04 

FIELD: physics, radio.

SUBSTANCE: invention concerns designing of radio electric devices (RED), particularly methods of spatial mini module manufacturing for REDs. Objective of the invention is achieved by adjustments to a method of spatial mini module manufacturing for RED. The method involves assembly and tuning of mini module board fragments in the form of small printed circuit boards with radio electronic components installed on them, combining of mini boards into a single construction, compound casting, establishing links between mini boards, and functionality test of obtained mini module. Adjustments include butted positioning of mini boards in a closed spatial parallelepiped pattern, further electric and mechanical interlinkage of mini boards by putting bridges between adjoining boards, functionality test of obtained mini module, compound casting to form external shell of the mini module, and second functionality check. One layer of multilayer small printed circuit boards is a screen, and screening layers of all mini boards with the same power conductor of the spatial mini module are connected electrically, while all radio electronic components sensitive to jamming are positioned on printed circuit boards in the closed space inside parallelepiped.

EFFECT: jam resistance, high packing density and mechanical durability of radio electronic components at low production labour costs, increased manufacturability and maintainability of assembled mini modules.
