Alternative Pb-Free Alloys Continue to Proliferate to Meet Market Demand

While Sn3.0Ag0.5Cu (SAC305) still dominates, alternative Pb-free solders continue to proliferate to meet market demand. PC vendors are encouraging suppliers to eliminate SAC305 to reduce cost (SAC305: $42/lb,SACX0307: $28/lb, SN100e: $22/lb, SN100C: $15/lb), high-rel OEMs are still not satisfied with SAC305 performance, and iNEMI is testing over ten non-SAC305 Pb-free alloys.
