Interface hermetic packaging method for electronic circuit module

Abstract

The invention discloses an interface hermetic packaging method for an electronic circuit module. By adoption of the interface hermetic packaging method, hermetic packaging problems of high-frequency sockets, high and low frequency electric connectors and cylinder heads or sunk screws frequently used in engineering can be solved. According to the following technical scheme, the interface hermetic packaging method is achieved by comprising the steps that according to assembly interfaces of connector assemblies and fasteners in the electronic circuit module, a high-frequency socket, insulators and a soldering ring corresponding to the high-frequency socket are firstly mounted; soldering rings are fixed to corresponding preset soldering ring holes; a sunk screw and a shape memory alloy ring are separately assembled to corresponding assembly interfaces, a soldering curve meeting requirements of the devices at the same time is set in a vacuum soldering furnace, powerful contraction generated by the heated shape memory alloy ring in the soldering process squeezes a cavity and an annular wall reserved at the interface of the sunk screw, and the high-frequency socket, a radio frequency electric connector, a feed through connector and a coaxial connector in the microwave and millimeter wave electronic circuit module are integrally packaged into the cavity through the sunk screw.

Description

technical field [0001] The invention relates to an interface design method that can simultaneously meet the airtight packaging requirements of high-frequency sockets, high-low frequency electrical connectors and cylindrical head or countersunk screws in the same electronic circuit assembly. Background technique [0002] With the increasing complexity of electronic systems, there is an urgent need for high-density, high-speed and high-reliability microelectronic components or components, which must be realized by using advanced IC devices and corresponding interconnection and packaging. Throughout the electronic packaging industry in recent years, electronic packaging technology continues to develop in the direction of ultra-high density, and ultra-high-density packaging forms such as three-dimensional packaging, multi-chip packaging (MCP) and system-in-package (SIP) have emerged. Packaging technology continues to evolve towards ultra-small size. [0003] As we all know, mor...
