This alloy is specifically formulated for lead-free Hot Air Solder Leveling (HASL) applications.
Key Features
– Designed for lead-free HASL soldering
– Contains nickel and germanium to improve fluidity and reduce oxidation
– Minimises copper dissolution and dross formation
– Produces flat, uniform surface finishes
– Compatible with both conventional 63/37 tin-lead and modern lead-free assemblies
– Operates at a slightly higher temperature than traditional tin-lead alloys
– Silver-free, offering cost savings without compromising quality
– Fine microstructure enables excellent wetting and performance on fine-pitch components
Composition and Specifications
SN100CL includes tin (Sn), copper (Cu), nickel (Ni), and germanium (Ge) to optimise solderability and mechanical strength. The addition of nickel and germanium enhances fluidity while reducing oxidation. This results in superior solder joint appearance and a longer solder bath life.
Applications
Ideal for electronics manufacturing requiring lead-free soldering solutions, SN100CL supports both legacy and modern assemblies. It excels in Hot Air Solder Leveling processes and fine-pitch component soldering, ensuring reliable and consistent results in PCB assembly.
