SAC305 is a lead-free alloy that contains 96.5 % tin, 3% silver, and 0.5% copper. This alloy falls under the JEIDA recommendation for lead-free soldering. When used in wave soldering, AIM’s SAC305 bar solder offers far superior fluidity as compared to other alloys and makes of bar, resulting in excellent flow. AIM’s SAC305 bar solder also produces less dross than other bar solder, wets well, provides superior joint strength, and offers superior copper dissolution rates. AIM’s SAC305 bar solder is 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.
