Model: SACX0307 (Sn99/Ag0.3/Cu0.7) ALPHA SACX0307 alloy for lead-free wave soldering wave soldering process in lieu Sn63/Pb37 alloys, characteristics including the production of good rate; infiltration speed; excellent weldability ; and dross generation lowest in its class, which will help reduce the overall cost. Furthermore, Vaculoy technology can effectively remove solder oxides contained to avoid welding defects caused by the dross. Features: 1) yield and SAC305, and anti-bridging better than Sn99.3/Cu0.7 alloy; 2) infiltration speed: A typical infiltration rate of 0.75sec, 0.65sec with SAC305's quite far superior to Sn99. 3/Cu0.7 alloy; 3) tin slag to produce the most in its class is the lowest; advantages: 1) reduce overall operating costs, lower material costs, higher yields and low dross generation; 2) good weldability; fast wetting speed; 3) very good flowability reduces bridging level; 4) have shown a variety of flux outstanding performance
