Example Embodiment

[0031] The present invention will be described in further detail below.

[0032] like Figure 5 , Image 6 As shown, a welding method for secondary degassing and sealing of an ultra-thin vapor chamber 1 comprises the following steps:

[0033] Fix the ultra-thin vapor chamber 1 with the fixture 2;

[0034] Use a pressure welding tool to perform pressure welding on the seal of the ultra-thin vapor chamber 1;

[0035] Laser welding is performed on the sealing part of the ultra-thin vapor chamber 1 by using a laser welding tool.

[0036] The existing welding method for the secondary degassing and sealing of the ultra-thin vapor chamber 1 reduces the sealing performance of the ultra-thin vapor chamber 1 after welding and sealing, thereby reducing the heat transfer efficiency of the ultra-thin vapor chamber 1, and the welding cost is high and the process is high. Complex, not conducive to mass production.

[0037] The welding method for the secondary degassing and sealing of th...

Abstract

The invention relates to a welding method for secondary degassing sealing of an ultrathin vapor chamber. The welding method for secondary degassing sealing of the ultrathin vapor chamber comprises the following steps of fixing the ultrathin vapor chamber by using a clamp; performing pressure welding on the sealing position of the ultrathin vapor chamber by using a pressure welding tool; and performing laser welding on the sealing position of the ultrathin vapor chamber by using a laser welding tool. A pressure/laser hybrid welding mode is adopted, the sealing strength of the ultrathin vapor chamber after the pressure welding can meet the requirement for the internal vacuum degree of the ultrathin vapor chamber, and the laser welding secondary sealing procedure continues to be performed on the basis that the sealing strength of the ultrathin vapor chamber is guaranteed through the pressure welding; the problem that the sealing performance of the ultrathin vapor chamber becomes poor after the ultrathin vapor chamber works for a long time is solved, the heat transfer performance of the ultrathin vapor chamber is improved, the machining cost is reduced, and the welding method for secondary degassing sealing of the ultrathin vapor chamber can be used for batch production.

Description

technical field [0001] The invention relates to the technical field of manufacturing ultra-thin vapor chambers, in particular to a welding method for secondary degassing and sealing of ultra-thin vapor chambers. Background technique [0002] With the rapid development of modern technology, all kinds of electronic components are developing towards the trend of miniaturization and high performance. At the same time, the heat flux of electronic components continues to increase, and the ensuing thermal control problems are gradually highlighted. , The continuous rise of the working environment temperature will degrade the performance of electronic components, reduce the reliability and greatly shorten the service life. [0003] The main structure of the ultra-thin vapor chamber includes a bottom plate, an upper cover plate, a liquid-absorbing core structure, a liquid injection pipe and a working medium. As a two-dimensional phase change heat transfer element, the ultra-thin vap...
