What is flux residue?

Soldering generates combustion residues simultaneously after the reaction! An explanation of troubles and their countermeasures.

Flux, which is often heard in the soldering process, is an auxiliary agent for soldering and plays a role in making soldering possible. This time, I will explain what flux residue is, which remains after soldering, as well as the troubles caused by flux residue and their countermeasures. The components that make up flux, such as rosin and activators, react with the oxide film on the metal surface during the soldering process, dissolving and removing the oxides, thus enabling soldering. However, at the same time as soldering, "flux residue" (the burnt remnants after the reaction) is generated. *For more detailed information, you can view the related links.
