Sn90Sb10

Features:


Lead-free solder, Sn90Sb10 melting point is 240/250℃

- High strength

- Good creep resistance

- Compatible with all types of flux

- High lead and high temperature solder alternative lead-free solder



Describe:


Sn-Sb alloys have a narrow melting range (240/250°C), good compatibility with existing solders, excellent mechanical properties, and their cost is significantly lower than that of Au-Sn, so they are usually used as a kind of High temperature lead-free solder is used. The increase of Sb content in the alloy will improve the mechanical properties of the solder, if the Sb content is too high, the solder will be brittle and have poor electrical and thermal conductivity, so the mass fraction of Sb in the commonly used Sn-Sb solder will not exceed 10%. Sn90Sb10 has slightly worse wetting properties than Sn63Pb37, but Sn-Sb alloy is the Sn-based alloy with the best creep resistance under low stress.

Operation details: 


- Solder taking:

   Use an anti-static jig to pick up the solder to prevent solder contamination and deformation.


- Flux Compatibility:

  Sn90Sb10 solder is compatible with the major no-clean and water-soluble electronic grade fluxes currently on the market.
