FAQ:

Q: What is the purpose of using flux while soldering?

A: Cleaning the dirt and oxidized layer on the metallic surface to be soldered. Reducing the surface tension and viscosity of molten solder to improve the wettability. When contact and spread on metal surfaces prevent metal from being re-oxidized at higher temperatures. Allow molten solder paste to form solid long-lasting electrical and mechanical joints

Q: How to make a flux for soldering do it yourself?

A: R (Rosin) – pure rosin,no activators,low activity,mildest WW (Water-White) – purest rosin grade,no activators,low activity,sometimes synonymous with R RMA (Rosin Mildly Activated) – contains mild activators,typically no halides RA (Rosin Activated) – rosin with strong activators,high activity,contains halides

Q: What is basic use of flux in soldering?

A: Solder flux is used to remove the metal oxide surfaces that, in the joining process, prohibit a bond between the metals. At soldering temperatures, flux chemically reacts with oxides to produce new, tarnish-free surfaces. The presence of metal oxide surfaces is a barrier to bond formation, so they must be removed with solder flux before joining.

Q: Do you use “flux” when soldering?

A: When soldering circuit boards, or other electrical / electronic devices, yes – you need to use flux. Fortunately, almost all solder for electronics use has an internal core of flux, so you usually don’t need. to add more. Subsequently, question is, do you have to use flux when soldering copper? Flux is a chemical which helps you solder. Flux prevents the copper from oxidizing as you heat the copper with the torch.
