Acid-core solder is for pipes, not electronics


There was a roll of acid-core solder on the electronics bench (Dutch boy brand lead free). Only ever use rosin core solder for electronics, never acid-core. Acid-core solder corrodes electrical connections and equipment. I am removing this solder to the metal room in case someone wants to use it for plumbing work.

This might have been what killed the wallet tip... :frowning:


Lol another item for the barbarian list. I’m telling you we could get a comic book made for each area on what barbarians do…don’t be a barbarian :slight_smile:

Even rosin core solder corrodes, that’s why the best practice is to clean the flux off of your solder joints. But yes, acid core is for pipes almost exclusively. It will eat through circuit boards far faster than rosin core can. The other reason you don’t use acid core on electronics is for the sake of the soldering iron itself. It’ll eat away at the tip’s coating, causing poor thermal transfer, resulting in cold solder joints.
