Description
The oxidation reducing effect of germanium in the FELDER NiGe solders is linked to the consumption of this element during the solder process. The ideal Ge-content inside the solder bath should be between 0,008 % and 0,015 %. The increased germanium content at 1000 ppm of FELDER ISO-Tin® “Sn99Ag+ High-Ge” makes an additional refilling of germanium concentrate unnecessary and therefore ensures a constant high germanium content inside the solder bath.
