Which are the advantages of soldering at lower temperature?
There are a number of advantages when working with lower temperatures compared to higher ones when soldering. First, there is a much lower risk of oxidation giving the iron tips durability while also improving the wettability and cleanability of the soldering iron tip. This also helps guarantee greater efficiency in heat transfers. Second, it prevents the direct burning of the flux right on the tip. Instead, the flux is activated while soldering. This helps minimize, if not completely eliminate, one of the perennial problems of DIYers turning their tips into charcoal black. This also helps retain the tip’s wettability. Third, it is much better and safer to work with lower temperatures especially when soldering sensitive electronics like PCBs and the like. Low-temperature soldering helps reduce the risk of excessive heat transfers so sensitive components don’t get easily damaged. Lastly, the whole process of soldering allows for the optimization of quality since there is better control of the temperature. This helps minimize if not eliminate scraps and reworks.
