SN100CLe® HASL Top-Up Alloy
SN100CLe is a premium lead-free solder alloy designed as a top-up for SN100CL solder baths used in Hot Air Solder Leveling (HASL) processes. This alloy is formulated to control copper content while increasing nickel levels to extend solder bath life and improve solder joint reliability. With 0.005–0.007% germanium and a higher nickel content than SN100CL, the SN100CLe lead-free solder alloy enhances fluidity, reduces oxidation, and minimizes dross formation.
Key Features
– Lead-free and RoHS compliant
– Specifically designed as a top-up alloy for SN100CL
– Controls copper levels alongside increased nickel content
– Improves solder bath life and reduces dross formation
– Enhances fluidity and wetting on printed circuit boards
– Ideal for lead-free HASL soldering applications
Composition and Specifications
The SN100CLe lead-free solder alloy contains Tin (Sn), minimal Copper (Cu) at 0.05% max, Nickel (Ni) between 0.13–0.17%, and Germanium (Ge) at 0.005–0.007%. This unique composition optimizes solderability and mechanical strength while maintaining bath stability. The alloy melts within a temperature range compatible with SN100CL, ensuring seamless integration during replenishment.
Applications
SN100CLe is ideal for manufacturers using SN100CL solder baths in electronics assembly. It supports lead-free HASL soldering to produce flat, bright, and reliable solder joints. This alloy is perfect for advanced electronics assembly lines requiring reduced maintenance, extended solder pot life, and consistent soldering quality. It ensures compatibility with both modern lead-free and some legacy tin-lead assemblies.
