High-density three-dimensional stacking and assembling method for electronic modules

Abstract

The invention provides a high-density three-dimensional stacking and assembling method for electronic modules. The stacking and assembling method comprises the following steps: completing parallel stacking for functional circuit boards, function circuit sub cards and a radiating plate, and forming a functional circuit module; completing assembling for a back mother board and a machine case back cover board, and assembling for a front mother board and a machine case front cover board; enabling multiple functional circuit modules to be placed horizontally, and perpendicularly stacking the functional circuit modules with a back mother board cover board module through a bottom board connector; coating a machine case left cover board, a machine case right cover board, a machine case upper frame and a machine case lower frame for forming a machine case body; enabling a three-dimensional stacked body to be fixed in the machine case upper frame and the machine case lower frame through locking strips that are positioned on the functional circuit boards; completing the assembling and stacking for the front mother board cover board module; and finally forming the high-density electronic module with an anti-severe environment function. Compared with the existing electronic module assembling method in severe environments, the high-density three-dimensional stacking and assembling method provided by the invention has the advantages of high assembling density, light structural weight, high radiating efficiency, high support for high-speed signals, strong shock-proof and anti-impact capability, and the like.

Description

technical field [0001] The invention belongs to the field of computers and provides a method for high-density three-dimensional stacking and assembling of electronic modules. Background technique [0002] The assembly of high-density electronic modules has always been one of the difficulties in computer design in harsh environments. On the one hand, it is required that the electronic module can increase the integration density and reduce the volume and weight as much as possible; on the other hand, it is required that the computer can work normally in harsh environments such as high temperature, strong vibration, and strong impact. [0003] Traditional high-density electronic module assembly adopts the "chassis-board" assembly method. First, complete the machine installation of each component of the chassis and the machine installation of the board and heat sink, then fix the motherboard in the chassis, complete the assembly of the panel connector, and finally insert the bo...
