SN100C Lead-free Solder
Trusted UK Manufacturer Since 1986
Since 1986, DKL Metals has proudly operated as an independent manufacturer and supplier of high-purity solder and alloy products. We serve as one of the UK’s leading providers of both tin/lead and lead-free solder bars. We deliver consistent quality to electronics and industrial sectors. Our dedication to excellence is reflected in our early achievement of the BS5750 Part 2 Quality Management System accreditation, a standard few in our industry attained at the time. We continue manufacturing solder bars to stringent national and international standards, supported by our fully equipped onsite laboratory. Always driving progress, we focus on enhancing lead-free soldering standards. This commitment led us, in 2002, to secure the exclusive UK manufacturing licence with Nihon Superior Co. for SN100C lead-free solder bars.
Exclusive Licensed Supplier of SN100C solder
As the UK’s only licensed manufacturer of SN100C solder bar, DKL Metals supplies one of the world’s most reliable and technically advanced solders. SN100C is a lead-free, eutectic alloy featuring a unique micro-alloy combination of tin, copper, nickel, and germanium. This alloy has gained global recognition for its superior performance in lead-free wave soldering and mass production of printed circuit boards for over 20 years.
Key Benefits of SN100C Solder
SN100C delivers a fluidity closely matching traditional tin/lead solder. This ensures smooth, icicle-free solder flow, minimizing defects like bridging and icicle formation. The presence of nickel refines the grain structure and stabilizes the intermetallic layer, resulting in shiny, strong solder joints. Meanwhile, germanium substantially reduces dross formation, cutting maintenance costs and increasing solder bath longevity.
Compared to other lead-free alloys, SN100C offers lower copper dissolution rates and reduced solder bath dross, making it highly cost-effective without compromising quality or reliability. It complies with IPC J-STD-006 standards and performs consistently across various soldering processes, including wave and selective soldering.

Frequently Asked Questions (FAQ)
Q: What is SN100C solder?
A: SN100C is a lead-free solder alloy manufactured with a unique blend of tin, copper, nickel, and germanium. Known for its excellent performance in wave soldering and electronics manufacturing, offering high reliability without using silver or lead.
Q: How does SN100C compare to SAC305?
A: SN100C is generally more cost-effective because it doesn’t contain silver, which is expensive. It also has lower dross formation, slower copper dissolution rates, and is less corrosive to soldering equipment than SAC305. This results in longer machine life and reduced maintenance costs.
Q: What are the key benefits of using SN100C solder?
A: SN100C provides smooth, icicle-free soldering with shiny, strong joints. Its eutectic nature replicates the fluidity of traditional tin/lead solder. Additionally, it reduces defects, lowers dross build-up, and improves solder bath longevity.
Q: What melting point does SN100C have?
A: SN100C has a melting point of approximately 227°C, which is similar to other common lead-free solder alloys, making it suitable for standard lead-free wave soldering processes.
Q: Is SN100C solder environmentally friendly?
A: Yes, SN100C is lead-free and contains no silver, making it an environmentally conscious choice for electronics manufacturing while maintaining high performance.
Q: Can SN100C be used in all wave soldering machines?
A: Yes, SN100C is compatible with standard wave and selective soldering equipment. Although the process parameters might need adjustment when transitioning from leaded solders or other alloys.
Q: Does SN100C require special maintenance?
A: While SN100C reduces dross formation compared to other alloys, maintaining proper flux coverage and solder bath composition is important to maximize solder pot life and quality.
