Solder Alloy SN100Ce
SN100Ce is the copper-free version of the SN100C solder. This re-fill solder can be used if the copper content in used solder baths is too high and needs to be reduced to the accepted level of 0.5 - 0.9%.
Product Advantages
- copper-free version of the micro-allying solder
- finer grain structure and shinier surface than conventional Sn99.3Cu0.7 alloys
- eutectic alloy (defined melting point at 227°C)
- reduction of dross formation
- very good wetting characteristics
- highly reduced dissolution rate of copper and other metals in comparison with conventional Sn99Cu1 alloys and as a result significantly increased service lives of the solder baths
- reduction of defect rate due to much lower tendency to form bridges
- optimum working temperatures from 260-270°C
Application
The use of SN100Ce 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 improved and no excess solder remains on the components. Bridge formation is
considerably reduced compared to standard solders. Furthermore, the formation of dross is significantly minimised. SN100Ce can also be used at elevated temperatures, e.g. in selective soldering systems.
