This alloy is renowned for its excellent soldering properties and mechanical strength, with a melting range between 217°C and 221°C (423°F and 430°F). It is specifically designed for surface mount technology (SMT), reflow soldering, and other demanding electronic assembly applications.
The addition of silver and copper enhances thermal and electrical conductivity, while also providing better mechanical strength and resistance to thermal fatigue. This ensures durable connections that can withstand the rigors of high-temperature cycling and mechanical stress.
SAC305 offers a balanced composition that optimizes performance and reliability in a wide range of applications.
