Wenn’s ums Löten geht When it’s about soldering Quand il s’agit du soudage Technical Data Sheet STANNOL® FLOWTIN® TSC New Lead-Free Solder Alloy for Electronic Application • Eutectic Solder (melting point at 217°C) • Good wetting performance ® • Fine grain and smooth surface better than ECOLOY TSC (Sn95.5Ag3.8Cu0.7) ® • Reduced dissolution of substrate metal compared to ECOLOY TSC • Easy disposal – no lead containing waste Application ® ® STANNOL FLOWTIN TSC was designed to eliminate the use of lead containing solders in electric and ® electronics manufacturing. Like with ECOLOY TSC solder it is necessary to adjust machine settings, temperature profiles, and other parameters to the requirements of a lead free process. But there is nothing to ® ® do when switching from ECOLOY TSC to FLOWTIN TSC, all settings and parameters remain the same. The properties of the solder joints are at least comparable or even better than tin lead. ® The physical properties of FLOWTIN TSC do not change compared to common tin/silver/copper solder. But ® ® there are differences between ECOLOY TSC and FLOWTIN TSC with micro additives. • • • The solder joint solidifies as fine grain metal; therefore the surface is shinier The dissolution of substrate metal is reduced The service life of solder is extended baths due to lower copper enrichment Product Range ® ® STANNOL FLOWTIN TSC is available as solder bars and solder wire 2,00 FLOWTIN TSC 0.1 µm/sec 1,80 1,60 y = -0,0002x + 1,6739 Durchmesser/mm 1,40 1,20 1,00 0,80 0,60 0,40 y = -0,001x + 1,7197 ECOLOY TSC 0.5 µm/sec 0,20 0,00 0 500 1000 1500 2000 2500 3000 time/ sec ® Radial dissolution of copper wire in FLOWTIN TSC solder bath @300°C The above values are typical and represent no form of specification.
