The manufacturing method of heat-dissipating vapor chamber

The present invention is a manufacturing method of heat-dissipating vapor chamber. The heat-dissipating vapor chamber includes an upper plate and a lower plate, which correspond to each other. The manufacturing method of main steps include: coating polymer materials at predetermined places of the upper and lower plates, and sending the upper and lower plates into the vacuum chamber at the same time, and evacuating in the vacuum chamber until the vacuum degree reaches the predetermined requirement. Then, the upper and lower plates are pressed together, so that the upper and lower plates form a vacuum heat-dissipating vapor chamber. Through the operation of the low-temperature process, the present invention does not require high-temperature welding and fusion during the process, nor does it need to prepare degassing pipes, clamping parts, etc., in addition to optimizing the manufacturing process, it can also reduce the use of materials and reduce the steps of manual operation. The present invention can achieve
