MacDermid Alpha Electronics Solutions ALPHA ® SnCX ® Plus 07

Silver-free lead-free alloy for wave, selective and rework applications. Product Overview ALPHA SnCX Plus 07 is a no-silver, lead-free alloy designed as a replacement for SnPb, SAC305, and other low-silver SAC alloys in wave soldering, selective soldering, lead tinning, and rework processes. This material has been engineered to minimize drossing and copper dissolution compared to silver-bearing alloys. It significantly reduces the total cost of ownership without compromising soldering performance or reliability, even on simple to moderately complex assemblies. Reliability Comparable to silver-bearing alloys and other enhanced alloys in thermal fatigue resistance and joint strength. Lowers Total Cost of Ownership Lowers total cost of ownership due to lower material costs, high yields, and a wide process window. Excellent Wetting Performance and Low Defect Rate Lowest in Class Dross Generation Consistent Performance Delivers consistent performance across different soldering processes.
