The utility model discloses a soldering tin liquid drip pipe, which comprises a heat-resistant pipe body, wherein an electric heating wire is arranged in the heat-resistant pipe body; the heat-resistant pipe body is wrapped by a heat insulating layer; and one end of the heat-resistant pipe body is open, and the other end of the heat-resistant pipe body is provided with a sealing soft sleeve. According to the soldering tin dropper liquid drip pipe, soldering tin is firstly melted in the soldering tin melting furnace, then the electric heating wire is heated, the open end of the heat-resistant tube body extends into the soldering tin liquid in the soldering tin melting furnace to squeeze the soft sleeve when the electric heating wire reaches a temperature which is slightly higher than the soldering tin melting point, the soldering tin liquid is sucked into the heat-resistant pipe body of the soldering tin liquid drip pipe by using atmospheric pressure, and then the soldering tin liquid drip pipe is moved to a p
