What is soldering flux?

Soldering flux is a chemical agent used to clean and prepare the surfaces of metals to be soldered. It helps to remove oxides and contaminants from the metal surfaces, allowing the solder to flow more easily and create a strong bond.

Flux is generally applied to the metal surfaces before soldering to improve the wetting and adhesion of the solder. It also helps to prevent oxidation of the metal surfaces during the soldering process.

There are different types of soldering flux available, such as rosin flux, water-based flux, and no-clean flux. Each type of flux has specific applications and benefits depending on the type of metals being soldered and the soldering process being used.

It is important to choose the right type of flux for the soldering job to ensure a strong and reliable solder joint. Flux residue should be cleaned off after soldering to prevent corrosion and ensure the long-term integrity of the solder joint.
