Description
To compensate the input of copper in hot air solder leveling systems filled with ISO-Tin® “SN100-403CL”, we recommend copper-free refill solder alloys. Particularly in HASL process, the copper input into the solder bath is so high, that nickel is used as a diffusion inhibitor. ISO-Tin®”SN100-403CLe(+)” compensates the increased nickel consumption in the plating bath.
