SN100Ce® Top-Up Alloy
SN100Ce is a premium lead-free solder alloy designed as a top-up or reviver for SN100C solder baths. This alloy contains nickel (about 0.05%) and germanium (around 0.006%), matching SN100C’s levels, but has a significantly reduced copper content. The SN100Ce lead-free solder alloy effectively dilutes copper concentrations to maintain solder bath balance while preserving the beneficial nickel and germanium that enhance fluidity and reduce dross.
Key Features
– Lead-free and RoHS compliant
– Specifically formulated to top-up SN100C solder baths
– Maintains nickel and germanium levels while reducing copper
– Minimises dross formation and copper dissolution
– Produces bright, smooth, and reliable solder joints
– Ideal for wave soldering and selective soldering applications
Composition and Specifications
The SN100Ce alloy typically contains Tin (Sn) as the base, nickel (Ni) 0.04% to 0.06%, and germanium (Ge) 0.005% to 0.007%. This composition supports optimum wettability and mechanical strength. The melting point is eutectic at approximately 227°C, ensuring smooth integration during top-up and replenishment.
Applications
SN100Ce is specifically designed for use in SN100C solder baths requiring copper dilution. Moreover, it is perfect for electronic assembly processes using wave soldering or selective soldering systems. By maintaining nickel and germanium levels, the SN100Ce lead-free solder alloy ensures stable solder bath performance while reducing defects, dross, and bridging. Consequently, this makes it a trusted choice for manufacturers seeking consistent, high-quality lead-free soldering.
