Ecorel Free™ 305-6G


SAC (SnAgCu) alloys are currently the industry choice because they have excellent soldering and mechanical properties. Of these alloys, the SAC 305 (SnAg3.0Cu0.5) is preferred because several evaluations (such as IPC SPVC reliability study) have demonstrated no significant statistical differences between SAC alloys with 3 to 4 % silver content and 0.5 to 0.7 % copper content. Patents, cost and soldering standardization considerations make the SAC 305 (SnAg3.Cu0.5) preferable for the majority of the industry.
