Understanding Soldering - Part 4: How to Use Flux When Soldering Electronics | Tempo
getting a good solder joint is in using a chemical cleaning agent known as flux before and during the soldering process
Flux is a chemical cleaning agent used before and during the soldering process of electronic components onto circuit boards.
purpose of the flux is to prepare the metal surfaces for soldering by cleaning and removing any oxides and impurities
protects the metal surfaces from re-oxidation during soldering and helps the soldering process by altering the surface tension of the molten solder
