As shown in fig. 1, the gas discharge tube is generally composed of electrodes and an insulating ceramic tube, wherein the distance between the electrodes is small to improve the electron emission capability, the discharge gap is filled with inert gas or other gases, active compound (electron powder) is coated on the effective electron emission surface of the electrodes, and lead wires (electrode leads) are arranged outside the electrodes.

The conventional reflow soldering and wave soldering are only suitable for mass production products, the equipment cost is high, the energy consumption is high, the waste is generated during waste, and a certain amount of test pieces are needed to verify the welding quality. The welding temperature of the manual welding iron is always higher than the high Wen Suilie temperature (300 ℃) of the ceramic of the discharge tube, and the manual welding iron is not easy to control, and the key sealing cavity of the gas discharge tube is extremely easy to damage, so that the discharge tube leaks gas and fails.
