How To Make Rosin Soldering Flux
In previous videos we compared different types of commercial flux but did you know its possible to make a simple and effective flux at home.
How to make rosin soldering flux. You can make a citric acid-based flux from ordinary household supplies that will prepare an object for soldering. Coat the wires with the soldering flux. Rosin core solder also acts as a flux.
In the soldering of metals flux serves a threefold purpose. How to tell if solder has rosin flux. Use a small paintbrush or your fingers to scoop up a small amount of soldering flux.
Next stir into the alcohol and let sit overnight. When stirring it in some will clump and not dissolve. Soldering the overlapped area is enough to get a conducting joint.
The hole is then filled with acid-base flux making up what is known as the acid core flux. It seals out air thus preventing further oxidation and by facilitating amalgamation improves wetting characteristics of the liquid solder. Some fluxes are corrosive so the parts have to be cleaned with a damp sponge or other absorbent material after soldering to.
You can stick a soldering iron in it to melt it or use a hot-air pencil to melt it a little just enough to allow a drop to drip off the block of rosin onto the work area. Soldering Paste FluxHow To Make At HomeSoldering Paste DIYSoldering Paste BanayeTechRizwan. There are different types of fluxes you can use to do that.
Rosin flux residuals may be left on the assembly or removed with a compatible solvent. Rosin consists mainly of abietic acid and combines with caustic alkalis to form salts rosinates or pinates that are known as rosin soaps In Wikipedia article about fluxes in the rosin. Only clean and easy-to-solder surfaces.
