ALPHA® SnCX Plus 07

Silver Free Alloy for Wave and Selective Soldering

ALPHA® SnCX Plus 07 is a No-silver lead-free alloy suitable for use as a replacement for SnPb, SAC305 and other low silver SAC alloys in wave solder, selective soldering, lead tinning and rework processes. SnCX Plus 07 has been engineered to minimize drossing and copper dissolution as compared to silver-bearing alloys. It significantly reduces the Total Cost of Ownership without sacrificing soldering and reliability performance on simple to moderately complex assemblies.

As with all Alpha Metals bar solder, Alpha's proprietary Vaculoy manufacturing process is used to remove certain impurities, particularly oxides. The product is further enhanced with special additives to further improve alloy physical and mechanical properties, reduce drossing, increase wettability and joint reliability.

Features & Benefits

  • Reliability – Comparable to silver bearing alloys and other enhanced Sn99.3Cu0.7 alloys in thermal fatigue resistance, and solder joint strength.
  • Yield – Excellent wetting performance and low soldering defect
  • Copper Erosion – Low erosion in long, hot exposure soldering process.
  • Dross Generation – Lowest in class due to the Vaculoy process in conjunction with the addition of a dross reducing agent.
  • Solder Fillet Surface – Smooth and bright with no surface crack
  • Lowers Total Cost of Ownership due to the lower material cost, high yields and wide process window.
  • Friendlier and less aggressive to solder pot material as compared to silver-bearing alloys.
  • Delivers good performance across different soldering processes.
