Alpha® SACX Plus® 0307

Wave Solder Bar

ALPHA® SACX Plus® 0307 is a next generation lead-free alloy suitable for use as a replacement for SnPb, SAC305 and other low silver SAC alloys including the original SACX 0307 in wave solder, lead tinning and rework processes. SACX Plus 0307 has been engineered for improved copper dissolution performance during the long hot exposure times associated with rework and lead tinning. The SACX Plus 0300 variant is used as a replenishment alloy in solder baths with elevated copper levels. 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 the addition of other materials designed to further reduce drossing, increase wetting speed and force and improve joint cosmetics.

Features & Benefits

  • Reliability - Comparable to higher Ag alloys (ie. SAC305) in thermal fatigue resistance, lap shear and pin pull performance.
  • Yield - Comparable to SAC305, superior performance for hole fill and SMT related defects compared to Ag free alloys like Sn99.3/Cu0.7.
  • Copper Erosion - Low erosion during long rework exposure times
  • Dross Generation - Lowest in class due to the Vaculoy process in conjunction with the addition of a dross reducing agent.
