The flux system Kristall 600 was specially developed for soldering tasks in the field of manual soldering. Due to its properties, this solder wire is of course also suitable for use in soldering robots. Although mildly activated, this solder wire ensures fast and reliable wetting on most surfaces used in modern electronics manufacturing. All low oxidized, easily solderable metal surfaces such as copper, brass or even tinned surfaces are suitable for safe solder joint formation. The Kristall 600 solder wire leaves low, transparent and electrically highly safe residues on the solder joint.
