Cl, Br and F are halogens that are traditionally present in soldering materials such as solder paste and solder wire, but also in soldering fluxes.
Halogens have the property of staying active on every temperature. That is why they are very interesting to use as activators to clean the surface that has to be soldered.
The question rises now: What is the influence of these halogens on the reliability of electronic ciruits that have been soldered with lead free alloys? |
