WebSAC305 is the lead-free standard alloy consisting of 96.5% tin, 3% silver, and 0.5% copper. Its silver content of 3% ensures optimal wetting properties and balanced properties in terms of thermal fatigue, strength of the solder connection, and resistance to mechanical stress. Properties of the SAC305 alloy Clear filters Flux classification WebThe CTE values of SAC305, SAC387 and Sn-3.5Ag increase by 8-16% after 30 days of aging, while the CTE values of SnCu, SnCu-Ge and SN100C solders increase by only 3-6%. The CTE evolution of lead-free solders can be explained by microstructural changes observed during isothermal aging, which causes coarsening of various phases of the solder.
