6/1/2023 0 Comments Flux definition![]() Rosin is a collection of naturally occurring acids, chiefly abietic acid and its homologs. Pine tar resin is dissolved in solvent and then distilled to yield the clear, water-white rosin used in soldering flux. The most basic soldering flux, one that has been used for over a thousand years, is the natural rosin derived from pine tar resin. It increases the wetting ability of the solder, causing it to flow more uniformly over surfaces without balling-up (dewetting). This article covers the types of fluxes available, the advantages and disadvantages of each, and options for flux removal.įlux aids in soldering and desoldering processes by removing oxide films which form on the surface of metals being soldered. That ensures the solder joint doesn’t crack or come loose even with the day-to-day wear-and-tear. When joining two metals in a soldering process, like used in PCB assembly, flux is required to achieve a true metallurgic bond.
