How To Make Soldering Flux Liquid

I found this great video on making your own flux for soldering.

How to make soldering flux liquid. It helps to clean and remove oxides and other impurities and thus helps in wetting. After soldering you may find that the flux has left residue. Take a liquid measuring cup and pour off 150ml of the Ethanol from the container.

Liquid flux is also very cheap and very available. For plumbing joints recommended acid flux when soldering pipes because acids are more prone to remove oxide layers. It works the same as the borax cone so needs to be mixed with water to create a smooth paste.

Solder flux is a very useful material that contributes to achieving a perfect soldering bond which is activated by the heat of the soldering operation to remove the last layer of oxidized metal so that the solder will wet the base metal and create a good joint its used in automatic PCB assembly and hand soldering and is mainly in cleaning the surface of PCB before soldering process. Well get you started and dont miss the giveaway at the end of the video. The solder flux carries the oxide under the components and can cause some resistances around your.

You dont need to be precise. It is basically used to clean surface of PCB before soldering process. To the left is a video showing the process of making your own flux.

This resin acts as a solder. 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. Rosin Flux is manufactured from a type of Resin obtained from pines and some other plants.

Some fluxes are corrosive so the parts have to be cleaned with a damp sponge or other. How to use liquid flux when soldering. Tenacity flux can be used for soldering at medium temperatures of 600 - 900ºc great for using with medium and hard solder.
