Sn96.5Ag3.0Cu0.5 Lead-Free Solder Wire
Sn96.5Ag3.0Cu0.5
Lead-Free Solder Wire
Sn96.5Ag3.0Cu0.5 lead-free solder wire, also known as SAC305 solder wire, is widely used in electronic assembly where reliable solder joints, stable wetting performance, and RoHS-compliant lead-free production are required. With a melting point of approximately 217°C and available diameters from 0.1mm, it is suitable for precision soldering, SMT rework, PCB assembly, LED electronics, and fine electronic components.
A reliable SAC305 solder wire for precision electronics.
SAC305 is one of the most commonly used lead-free solder alloy systems in modern electronics manufacturing. The combination of tin, silver, and copper provides good wetting behavior, mechanical strength, thermal fatigue resistance, and stable solder joint performance. This solder wire is suitable for both hand soldering and automatic soldering processes, especially where fine wire diameter and consistent feeding are required.
