SN100C  (Sn-Cu-Ni+Ge)

The innovative and stabilised tin-copper alloy which is lead –and silverfree, works under an accepted temperature of 250°-260° in wave soldering.  As a result of new regulations set by the RoSH directive and WEEE, Sn100C offers valuable environmental advantages.

By trace addition of Ni (nickel) and Ge (geranium) on the base (Sn-0.7Cu) Sn100C offers many advantages:

• Ecologically sound.
• Does not contain silver or bismuth, and therefore it is cheaper.
• Reduction of oxidation on the surface => optimal fluidity and wettability.
• Remarkable less copper erosion than other alternative lead-free solders.
• Reduction of icicle -and bridge formations.
• Smooth, clear and bright uniform structure.
• No micro-cracks.
• Good through hole penetration.
• Does not require nitrogen atmosphere.
• Does not erode the copper of the holes, pads and lanes.
• Easy control over the copper in the solderbath because of low rate of copper leaching.
• Dross-rate is smaller or equal than tin-lead solder.

Because of the workability and trustworthiness, Sn100C is applied in a wide range of consumer products. (from battery chargers to household devices).  But also developers for high end products (such as audio -and recording systems) are aware of the capacity of Sn100C. The superior sound quality should can only be achieved because of the higher electrical conductivity of Sn100C.

When compared to SAC, Sn100C has better thermal resistance, higher electrical conductivity and a slower rate of copper absorption in the solder bath.
