Best choice for lead-free wave soldering

SN100C is a lead-free solder alloy developed by Nihon Superior in Japan that is comprised of tin-copper-nickel + germanium. SN100C offers user-friendly properties and has been proven in commercial production since 1999. The result of these advantages is that SN100C offers high-throughput and the lowest cost of ownership as compared to any other lead-free solder alloy.


SN100C at a glance
  • Does not contain silver or bismuth.

  • Eutectic alloy.

  • Bridge-free and icicle-free soldering.

  • Smooth, bright, well-formed fillets, free of micro-cracks, unaffected by the cooling rate.

  • Good through-hole penetration.

  • Good topside fillet formation.

  • Dross rate equal or lower than tin-lead solder.

  • Does not require a nitrogen atmosphere.

  • Does not erode copper from holes, pads and tracks.

  • Low rate of copper dissolution for better control the copper content of the solder bath.

  • Lower aggressiveness to solder pot materials as compared to tin-silver-copper alloys.

  • Also performs well in selective and dip soldering.


The Bottom Line

The cost of running a line with SN100C is always lower than the cost of running the same line with SAC305.

  • Bar Solder

  • Solder Bath Top-Off Alloy (SN100Ce)

  • Cored and Solid Wire Solder

  • Other forms such as Solder Paste and Spheres
