Material Notes:

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.Uses include:Fiber to Ferrule SolderingLaser Die AttachHermetic Packaging & SealingWetting & Sealing Laser OpticsThermal ManagementInformation provided by AIM Specialty Materials.
