How To Diy Soldering Flux
It is basically used to clean surface of PCB before soldering process.
How to diy soldering flux. I tried it a few times and wrote this tutorial when when I got a consistency I liked. Table salt is one ingredient of homemade silver soldering flux. Some fluxes are corrosive so the parts have to be cleaned with a damp sponge or other absorbent material after soldering to.
Add some isopropyl or denatured alcohol to a small jar or plastic medicine bottle. You have made one litre of flux remover that quantity should suffice for quite some time. I would have added a few drops of glycerol if there had been any nearby but the flux was fine as it was.
DangPro shows you how to create your own solder flux. It does not even require you to thoroughly clean the surface of the metal. This makes a mild acid.
Spread the flux over the area you will be soldering making sure to cover the wires fully. Flux is a wonderful goo that makes soldering faster and easier. I usually coat newly etched boards with a thin layer of pure rosin flux not RMA flux and this makes them easier to solder and protects them from oxidizing.
Dont overheat and stop as soon as the solder starts to appear as a ring around the coupling otherwise itll all run out of the joint. It seals out air thus preventing further oxidation and by facilitating amalgamation improves wetting characteristics of the liquid solder. In a pinch you can use a solution of white vinegar and salt.
Oh and did I say. Rosin Flux is manufactured from a type of Resin obtained from pines and some other plants. Add some chips of Kalifonia resin flux.
