How To Make Rosin Soldering Flux

The acid core is primarily solder made into a wire form that has a hole as its core.

How to make rosin soldering flux. Coat your wires with soldering flux. Soldering the overlapped area is enough to get a conducting joint. Then make a blob of solder on the iron and wait till the flux evaporated.

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. It is necessary for metal surfaces to be prepared in order to adhere to any solder placed on them. No Clean NC flux combines rosin.

Coat the wires with the soldering flux. The solvent will dissolve the rosin. Add your solvent start with a small amount and keep adding until you are happy with the way your flux behaves.

Using a paintbrush or a finger apply a generous amount of solder flux on the joint and cover the area. To make a batch simply crush the rosin into a powder with a hammer put into an envelope first before pounding. Rosin flux residuals may be left on the assembly or removed with a compatible solvent.

Place the rosin inside the jar if you cant wait for it to dissolve youd want to grind up the crystals to a fine dust this will vastly improve the time it takes to dissolve from hours to minutes. 10 to 15 pine cones with pine tar sap on the ends of the cone leaves found around pine trees 1 Quart Denatured Ethyl Alcohol found in the wild at a hardware store or you could distill your own Tools required. DangPro shows you how to create your own solder flux.

If the rosin is in big chunks this process may take some time. Spread the flux over the area you will be soldering making sure to cover the wires fully. Choose the diameter of the solder based on the size of the job.
