Product Description
0.8mm 1.0mm SMD Soldering Lead 63/37 Pb37Sn63 100g 200g per Roll for PCB Assembly
Introduction
When it comes to PCB assembly, choosing the right SMD soldering lead is crucial for ensuring strong, reliable connections. The SMD soldering lead 63/37 (Pb37Sn63) is a popular choice among electronics manufacturers and hobbyists due to its excellent wetting properties and low melting point. Available in 0.8mm and 1.0mm diameters, with options of 100g and 200g per roll, this solder wire is ideal for precision soldering tasks.
In this article, we will explore the benefits of using SMD soldering lead for PCB assembly, its composition, and why the 63/37 (Pb37Sn63) alloy stands out among other solder types.
What is SMD Soldering Lead?
SMD soldering lead is a specialized type of solder wire designed for Surface Mount Device (SMD) applications. Unlike traditional soldering wires, SMD soldering lead for PCB is formulated to provide smooth, clean joints with minimal residue. The SMD soldering lead 63/37 variant, composed of 63% tin (Sn) and 37% lead (Pb), offers a eutectic mixture, meaning it melts and solidifies at a single temperature, reducing the risk of cold solder joints.
Key Features of SMD Soldering Lead 63/37
Eutectic Alloy: The soldering lead Pb37Sn63 has a melting point of 183°C (361°F), making it easy to work with.
Excellent Flow Characteristics: Ensures smooth application on PCBs.
Minimal Splatter: Reduces the risk of bridging between components.
Available in 0.8mm and 1.0mm: Suitable for both fine-pitch and general soldering.
100g and 200g per Roll: Convenient packaging for different project sizes.
Why Choose SMD Soldering Lead for PCB Assembly?
1. Superior Wetting Properties
The SMD soldering lead 63/37 provides excellent wetting, ensuring strong adhesion between components and PCB pads. This is particularly important for SMD soldering lead for PCB assembly, where precision is key.
2. Reduced Risk of Cold Joints
Since the soldering lead Pb37Sn63 is eutectic, it transitions directly from liquid to solid without a pasty phase, minimizing the chances of weak or cold solder joints.
3. Ideal for Fine-Pitch Components
The availability of SMD soldering lead 63/37 0.8mm makes it perfect for small SMD components, while the 1.0mm variant is better for larger joints.
4. Convenient Packaging
Whether you need a 100g roll for small repairs or a 200g roll for larger projects, SMD soldering lead 63/37 100g and 200g options provide flexibility.
Applications of SMD Soldering Lead 63/37
The SMD soldering lead for PCB is widely used in:
Consumer Electronics: Smartphones, laptops, and tablets.
Automotive Electronics: ECU boards and sensor modules.
Industrial Control Systems: PLCs and automation devices.
DIY Electronics Projects: Prototyping and repairs.
Comparison: 0.8mm vs. 1.0mm SMD Soldering Lead

Tips for Using SMD Soldering Lead Effectively
Use the Right Temperature: Set your soldering iron between 300°C–350°C for best results with SMD soldering lead Pb37Sn63.
Apply Flux if Needed: While 63/37 solder has good flux core, extra flux can help with oxidation-prone surfaces.
Choose the Correct Diameter: For fine components, 0.8mm is ideal, while 1.0mm works better for larger joints.
Store Properly: Keep your SMD soldering lead for PCB assembly in a dry place to prevent oxidation.
Conclusion
For anyone involved in PCB assembly, the SMD soldering lead 63/37 (Pb37Sn63) is an excellent choice due to its reliability, ease of use, and versatility. Whether you need the 0.8mm variant for precision work or the 1.0mm for general soldering, and whether you prefer 100g or 200g per roll, this solder wire ensures high-quality connections every time.
By selecting the right SMD soldering lead for PCB, you can enhance soldering efficiency, reduce defects, and achieve professional-grade results in your electronic projects.
