Gas fluxIt is a highly active compound that is not added to the molten solder under gas phase conditions. During the welding process, these compounds form solder particles and create solder droplets through the transmission of gas or liquid in the gas flux. During the condensation of the solder droplets, a strong gas flow generated by the gas or flux promotes the condensation of the droplets into a liquid form of flux. Due to the presence of a large amount of oxygen in the gas flux, this oxygen can undergo redox reactions with compounds in the flux, causing the decomposition of compounds in the solder particles. Due to its oxidizing nature, the oxygen content in the flux particles is high, resulting in good welding effects.

Gas flux is mainly used for soldering electronic components. When soldering electronic components, flux is applied between the component pins and pads, allowing solder to melt and perform welding. Since gas flux can adsorb solder micro-particles onto component pins during the melting process, it can also remove oxides such as paint and dust from the surface of components to achieve a clean surface.

　　Gas fluxThere are many types; it helps with welding and increases the mechanical strength of the weld surface. During welding, it can form an oxide protective layer on the surface, ensuring the mechanical properties of the welded metal. When using it, appropriate flux must be selected. When using gas flux, ensure that the concentration of effective components is between 1.5% and 3%, and that the content of effective components does not fall below 1.5%. The welding current is generally 10-30a.

1. Components of gas flux: The main components of the flux are rosin, solder powder, anti-aging agents, etc.

　　2.Gas fluxViscosity: Generally 20-60s, forming a thin film on the surface of the solder joint for protection.

3. Process parameters: Welding temperature is generally between 220-270 degrees, and welding speed should be fast.

　　4.Gas fluxUsage time: Generally 2-10 minutes, depending on usage conditions.
