How To Make Soldering Flux

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.

How to make soldering flux. With the help of solders connect the wires radio nodes and small parts. Touch the already hot soldering iron with the soldering gun onto the wire to heat the cross-section. In electronics it is crucial to use flux when soldering in order to make solid and shiny joints.

Flux is designed for soldering metals. Mix together 60 ml 2 fl oz Borax 60 ml 2 fl oz TSP and 90 ml 3 fl oz of boric acid in a pan. Look around the edges of the pipe for any large lumps of flux and brush them away.

Here is a simple and easy homemade rosin flux made from pine cones. A good flux keeps the metal surface clean and oxide-free. Trying to use a solid core solder without flux will result in a practically useless joint.

It removes oxidation from the surfaces to be soldered. Push the soldering gun onto a side of your wires to melt flux. Cover the container and allow the mixture to sit for at least 8 to 12 hours.

Do nothing until all of the juice has strained through. Well get you started and dont miss the giveaway at the end of the video. The citric acid flux you have made can now be used to prepare metal for soldering.

You dont need to be precise. Place the strainer in the kitchen sink for washing later. Fluxes can be made from hydrochloric acid zinc chloride or rosin.
