How To Make Soldering Flux Paste

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

How to make soldering flux paste. To make liquid soldering flux gather all the components firstThen make sure that lemon are you using is fresh so that it can give more citric acid than usual. DangPro shows you how to create your own solder flux. Metal workers artists and crafters all rely on flux to complete many of their projects.

First put the solder paste on the pads and then use an needle or dental pick to carefully move excess on to the pad or remove it. Once combined the paste is a gray putty-like material. 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.

Removing any oxidized metal from the surfaces to be soldered. For flux for electrical soldering use rosin-based flux to make solid joints. Only two ingredients are required.

To make a larger quantity double the ingredients -- but always maintain the 223 ratio. The first method is by using a stencil. Table salt is one ingredient of homemade silver soldering flux.

I am waiting for a shipment of liquid flux currently and was just curious if this is a feasible hold-over. Good for perhaps 200 smd joints. The stencil allows you to apply solder paste only in the areas you want.

I am wondering if anyone has any experience with diluting flux paste into a less viscous form using isopropyl alcohol. 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. In the soldering of metals flux serves a threefold purpose.
