Problems solved by technology

During the soldering process of electronic components, it is necessary to melt the solder in the solder tank in advance. These molten solders need to be shielded and protected to avoid oxidation in the air, which will affect the soldering quality of electronic components.
The method of using a closed container to protect the molten solder will cause oxidation of the solder due to the presence of a small amount of air in the container, which cannot completely solve the oxidation problem

Abstract

The invention relates to the technical field of chemical industry, in particular to an efficient soldering tin protective agent. The efficient soldering tin protective agent is prepared from, by weight, 5-20% of high-viscosity dimethicone, 5-10% of palmitoleic triolein, 5-10% of arachidonic acid, 5-10% of liquid polybutylene, 40-50% of vacuum residue and 0.5-2% of amine antioxidant. The raw materials are mixed and molten into uniform grease at the temperature of 100-140 DEG C. The efficient soldering tin protective agent is stable in performance.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a high-efficiency solder protectant. Background technique [0002] With the development of the electronics industry, the amount of solder is increasing. Soldering is one of the most important processes in the assembly of the electronics industry. Its quality directly affects the reliability and stability of electronic products. Especially in the molten state, they are easy to react with oxygen in the air to form a denser layer. Oxide film. The oxide film can prevent the tin or tin alloy melt from being further oxidized when the tin or tin alloy melt is in a static state. During the soldering process of electronic components, the solder needs to be melted in the solder pot in advance, and the molten solder needs to be shielded to avoid oxidation in the air, which will affect the soldering quality of the electronic components. The method of using a closed container to ...
