Problems solved by technology

That is to say, in the driving mode of the electromagnetic pump, the pipe material may crack due to the erosion of liquid metal after a period of use, and eventually cause the heat dissipation system to fail
Moreover, since liquid metal is a conductive material, the leaked liquid liquid metal will also cause a short circuit on the circuit board, resulting in a substantial failure

Description

Technical field [0001] The invention relates to the technical field of alloys, in particular to a gallium alloy. Background technique [0002] The main factors that determine heat dissipation and heat conduction in electronic chips are: chip integration density, copper foil thickness, trace width and so on. In the actual use process, the application environment of the product, the production process of the circuit board and the quality of the board should also be considered. The increase in chip integration density will cause the axis of the circuit board to generate heat after continuous current, which will cause the chip temperature to rise. What is especially serious is that the rise in temperature not only activates the self-protection mechanism of the chip, but also deforms the substrate when the temperature rises to the allowable temperature of the substrate, which affects the bonding force between the copper foil wire and the substrate, and ultimately leads to structural ...
