How To Make Soldering Flux Paste

The tip of the iron is then heated up in order to melt the solder paste.

How to make soldering flux paste. Gets like graysilver toothpaste. It helps to clean dirty parts and improves the surface tension of the molten solder so it stays on the pads instead of running between them called bridging. Add approximately 250 ml 1 cup of water to the ingredients in the pan.

It seals out air thus preventing further oxidation and by facilitating amalgamation improves wetting characteristics of the liquid solder. Flux is a substance that comes in powder paste and liquid forms. For flux for electrical soldering use rosin-based flux to make solid joints.

Flux is a wonderful goo that makes soldering faster and easier. The alcohol will dissolve the pine tar from the leaves. 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.

Once this has happened strain the mixture to remove the leaves and any other small pieces of debris. The first method is by using a stencil. Step one in how to make silver solder paste is to use a small set of scales to measure out the correct amounts of fine silver copper and zinc to make your own silver solder.

I am wondering if anyone has any experience with diluting flux paste into a less viscous form using isopropyl alcohol. The stencil allows you to apply solder paste only in the areas you want. Place the stencil over the board and apply the solder paste through this.

Once combined the paste is a gray putty-like material. 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. You can now use the pine tar-alcohol mixture as your flux.
