How To Make Rosin Soldering Flux

I then touched it to the pcb where the fluxes was.

How to make rosin soldering flux. 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. Then I covered it in 99 isopropyl alcohol swirled it around for a minute or two and left it overnight to dissolve. The rosin category is further divided three subcategories.

Only two ingredients are required. For plumbing joints recommended acid flux when soldering pipes because acids are more prone to remove oxide layers. To make a homemade rosin flux place the pieces of rosin in a container and cover them with a solvent such as isopropyl alcohol or nail polish remover.

To make a batch simply crush the rosin into a powder with a hammer put into an envelope first before pounding. Next stir into the alcohol and let sit overnight. Soldering the overlapped area is enough to get a conducting joint.

When I get some more rosin ill make a RMA flux with with citric acid as the activator. The hole is then filled with acid-base flux making up what is known as the acid core flux. Add your solvent start with a small amount and keep adding until you are happy with the way your flux behaves.

You can stick a soldering iron in it to melt it or use a hot-air pencil to melt it a little just enough to allow a drop to drip off the block of rosin onto the work area. Rosin flux is primarily composed of natural resin extracted from the oleoresin of pine trees and refined. Flux is first applied to the surface of such objects in order for them to take the soldering.

Well get you started and dont miss the giveaway at the end of the video. No Clean NC flux combines rosin. We try it out and then test it by soldering a 28pin SOIC chip.
