The RF4 RF206D is a professional-grade, high-purity solder wire designed for precision electronics assembly and repair. This 200g spool features a Sn63/Pb37 (63% tin, 37% lead) eutectic alloy, which delivers exceptional wetting performance and bright, reliable solder joints . The "little residue" formulation ensures minimal post-solder cleaning, making it ideal for mobile phone motherboard repair, BGA rework, and SMD soldering applications.
Manufactured in Guangdong, China, with CE certification, this solder wire is engineered for clean, efficient soldering with low spatter and fast spreading .
Key Features
1. High-Purity Sn63/Pb37 Eutectic Alloy
The 63/37 tin-lead ratio provides a sharp melting point at 183°C (361°F) with no plastic phase, reducing the risk of cold joints and ensuring consistent, professional results .
2. Little Residue / No-Clean Formulation
Features a rosin core with minimal residue, allowing for clean soldering without extensive post-solder cleaning. The low-residue formula means the remaining flux is non-corrosive and non-conductive .
3. Excellent Wettability and Fast Spreading
Engineered for superior flow characteristics, enabling the solder to spread quickly and evenly onto pads and component leads, even through small holes .
4. Smooth, Oxidation-Resistant Joints
Produces bright, smooth solder joints with good conductivity and resistance to heat fatigue, ensuring long-term reliability .
5. Available in Multiple Diameters
The RF206D is available in various diameters to suit different applications:
- 0.3mm – Ultra-fine pitch, micro-soldering
- 0.4mm – Fine-pitch SMD, precision work
- 0.6mm – General SMD soldering, phone motherboard repair
- 0.8mm – Through-hole components, general PCB assembly
- 1.0mm – Larger pads, connectors, wire splicing
