- Eutectic alloy (defined melting point at 227 °C)
- Good wetting characteristics
- More finely grained and smoother surface than conventional Sn99Cu1 alloys
- Reduced dissolution rate in comparison with conventional Sn99Cu1 alloys and as a result significantly increased service lives of the solder baths.
Application The use of FLOWTIN TC as wave solder requires a solder bath temperature of approx. 260 to 280 °C. The use of inert gas means a significant extension of the process window. The wetting of the solder is made easier and on exit from the wave, no excess solder remains attached to the components. The dross formation is also considerably minimised. FLOWTIN TC can also be used in selective soldering systems.
