Flowtin TC offers the following advantages:

Advanced solder for wave soldering
Less dross formation
Less solder bath maintenance
Avoids oxide related soldering defects
Eutectic solder (melting point at 227 °C)
Operates best at 260-270°C solder bath temperatures
Made in Germany

Solder Bar FLOWTIN TC Lead Free

Solder Bar FLOWTIN TC (Sn99Cu1 and Sn99.3Cu0.7) is a lead-free, eutectic solder analogous to ISO 9453:2006 (alloy number 401) with micro-alloy components (<500 ppm) and deoxidation additives. The FLOWTIN TC alloy is a micro-alloyed solder based on the alloy Sn99Cu1. The new alloy has been further developed from FLOWTIN TC to minimise the dross formation on solder bath surfaces which occurs with normal, lead-free alloys during soldering in air. As soldering under inert gas (N2) is also never completely oxygen-free, the bath surface also remains clean here for longer.

PRODUCT ADVANTAGES

Fine-grained, smooth and shiny surface of the solder joint
Reduced dissolution of copper from conductor tracks and component connections
Increased service life of solder baths due to lower copper enrichment
Reduction of dross due to deoxidation additive
Avoidance of solder defects caused by oxides
Significantly reduced maintenance costs for the soldering machines
Optimal for bath temperatures of 260-270 °C
Made in Germany

APPLICATION

The use of solder bar FLOWTIN TC as wave solder requires a solder bath temperature of approx. 260 to 270 °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 minimized. FLOWTIN TC can also be used in selective soldering systems.
