Wenn’s ums Löten geht When it’s about soldering Quand il s’ agit du soudage Technical Data Sheet STANNOL® FLOWTIN® TC New Lead-Free Solder Alloy for Electronic Application • Eutectic Solder (melting point at 227°C) Good wetting behaviour Fine grain and smooth surface better than ECOLOY® TC (S-Sn99Cu1) Reduced dissolution of substrate metal compared to ECOLOY® TC (S-Sn99Cu1) Easy disposal – no lead containing waste. • • • • Application ® ® STANNOL FLOWTIN TC solders have been designed to eliminate the use of lead containing solders in ® electric and electronics manufacturing. Like with ECOLOY TC 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 TC to FLOWTIN TC, 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 TC do not change compared to common tin/copper solder. But there are ® ® differences between ECOLOY TC and FLOWTIN TC with micro additives. • The solder joint solidifies as fine grain metal; therefore the surface is shinier • The dissolution of substrate metal is reduced • The extended service life of solder baths due to smaller copper enrichment Product Range ® ® STANNOL FLOWTIN TC is available as solder bars and solder wire Dissolution rate, Cu-wire at 300°C 2,00 1,80 metal removal/mm 1,60 1,40 FLOWTIN TC 0,53 µm/sec 1,20 1,00 0,80 0,60 0,40 ECOLOY TC 0,9 µm/sec 0,20 0,00 0 500 1000 1500 2000 2500 3000 3500 time/seconds ® Radial dissolution of copper wire in FLOWTIN TC solder bath @300°C The above values are typical and represent no form of specification.
