Choose Well When Soldering
Based on an original publication by Hakko
Soldering can be described as gluing with molten metal. Two or more metal objects are joined together by heating them and then applying solder. The solder melts onto the joint (wetting) then, cools and bonds them together.
As technicians know, “flux is your friend” and removes oxides and prevents new build-up. Oxidation occurs when oxygen in the air reacts with the hot metal and forms a covering layer over the metal that keeps solder from sticking.
