SN100C® Solder Alloy
SN100C is a premium lead-free solder alloy designed for wave and selective soldering applications. It delivers excellent solderability, smooth wetting, and bright, reliable joints. This silver-free alloy reduces copper erosion and dross formation, providing cost-effective performance without sacrificing quality.
Key Features
– Lead-free and RoHS compliant
– Smooth wetting for clean joints
– Silver-free, reducing material costs
– Minimised copper erosion for longer joint reliability
– Compatible with wave and selective soldering processes
– Ideal for electronics manufacturing and PCB assembly
Composition and Specifications
SN100C typically contains Tin (Sn), Copper (Cu), Nickel (Ni), and Germanium (Ge) to optimise solderability and mechanical strength. It exhibits a melting temperature range of approximately 227 – 230 °C, making it reliable for modern electronics assembly.
Applications
Suitable for use in commercial and industrial electronics, including automotive electronics, telecommunications, consumer electronics, and industrial control systems. SN100C solder bars provide low smoke and minimal fumes during soldering, enhancing operator safety and workplace conditions. The alloy also offers excellent joint strength and thermal fatigue resistance.
