AIM SAC305 lead-free solder. Sn96.5 / Ag3 / Cu0.5. 1 lb. roll, 1mm (0.04") diameter. Offers far superior fluidity as compared to other alloys resulting in excellent flow. Provides superior joint strength and offers superior copper dissolution rates. Alloyed in the proprietary Electropure method that results in a low drossing, high wetting solder. The Electropure process reduces suspended oxides in the solder, thus reducing drossing, improving flow and reducing bridging during soldering. SAC305 may be used with most existing equipment, processes, coatings, and flux chemistries.
