Description
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. Alpha SnCX Plus 07 has been engineered to minimize copper dissolution as compared to silver-bearing alloys and to improve total cost of ownership.
Features
Benefits
Features
- Reliability - comparable to silver-bearing alloys (i.e SAC305) an other enhanced Sn99.3.Cu0.7 alloys in thermal fatigue resistance, lap shear, and pin pull performance
- Yield - excellent production yields; outperforms Sn99.3.Cu0.7 based materials
- 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
Benefits
- Lower total cost of ownership due to the lower material cost, high yields and low dross generation
- Excellent mechanical reliability
- Provides very good solderability due to the fast wetting speed
- Reduces erosion of copper plating during rework which improves reliability
