Solid rosin can be placed inside the flux or solder it?? What's the function?
In general, rosin is a kind of flux used in electronic welding. It belongs to resin flux and has better effect than inorganic and organic fluxes. It is one of the most commonly used fluxes.Rosin is put in solid flux, the welding flux has auxiliary heat conduction, removing the oxide, reduce the surface tension of welding material, welding material removal is surface oil, increase the welding area, prevent oxidation of "and so on, especially the first two, to improve the welding the effect of great help.
What is solid rosin? Isn't that just to protect the solder from being oxidized and to restore the solder that has been oxidized? So it's better to put it in the soldering flux. But this is not to say that it is not allowed to put in the stove inside, because the excess solder also need to protect and restore[answer added]:In practice, it is convenient to use rosin containing solder wire!
What do you want to achieve? I'll fix it for you.
