When it comes to reliable soldering for electronics, the quality of solder wire plays a crucial role in ensuring strong, long-lasting connections. Our 1.6mm 60/40 Tin Lead Rosin Core Flux Solder Wire is engineered for superior performance in PCB assembly, wiring, and electronic repairs. With a 60% tin and 40% lead composition, this solder provides excellent wetting properties, smooth flow, and durable joints. Packed in a convenient 1kg reel, it is an ideal choice for professionals, hobbyists, and manufacturers who demand precision and reliability.
1. Optimal Tin-Lead Ratio for Strong Joints
The 60/40 tin-lead blend is one of the most widely used solder alloys in electronics due to its eutectic properties—meaning it melts and solidifies at a single temperature (around 183°C/361°F). This ensures:
Smooth melting and solidification without a "pasty" phase, reducing the risk of cold joints.
Excellent wetting ability, allowing the solder to flow evenly over components and PCB pads.
Strong mechanical and electrical connections, essential for circuit reliability.
2. Rosin Core Flux for Effortless Soldering
This 60/40 tin features an integrated rosin flux core, which:
Prevents oxidation during soldering by cleaning metal surfaces.
Improves solder flow, ensuring smooth and even joints.
Reduces the need for additional flux, making soldering faster and more efficient.
Minimizes solder splatter and residue, keeping PCBs clean.
3. 1.6mm Diameter – Perfect for General Electronics Work
The 1.6mm thickness makes this 60 40 tin lead rosin core flux solder versatile for:
Through-hole component soldering (resistors, capacitors, connectors).
Larger surface-mount (SMD) soldering where a thicker wire is needed.
Wire splicing and general electronic repairs.
4. High-Quality Manufacturing & Consistency
Made in China under strict quality control for purity and performance.
Consistent alloy composition for reliable soldering every time.
Minimal impurities, reducing the risk of solder bridges or weak joints.
This solder wire is widely used in:
✔ PCB assembly and repair
✔ Consumer electronics manufacturing
✔ Automotive electronics
✔ DIY projects and hobbyist electronics
✔ Electrical wiring and connections
While lead-free solder (such as SAC305) is required in some industries due to RoHS compliance, 60/40 tin-lead solder remains popular for its superior workability and reliability:
Feature | 60/40 Tin-Lead Solder | Lead-Free Solder (e.g., SAC305) |
Melting Point | 183°C (361°F) - 190°C | 217-220°C (423-428°F) |
Wetting Ability | Excellent | Good (requires higher temps) |
Joint Strength | Strong & ductile | More brittle |
Workability | Easy to use | Requires more skill & flux |
Cost | Affordable | More expensive |
*For non-RoHS applications, 60/40 solder remains the best choice for ease of use and reliability.
To achieve the best results:
1. Clean the surfaces – Ensure PCB pads and component leads are free from oxidation.
2. Set the right temperature – Use a soldering iron at 300-350°C (572-662°F).
3. Apply solder correctly – Touch the 60/40 tin to the joint, not the iron tip, for optimal flow.
4. Avoid excessive heat – Prolonged heating can damage components or PCB traces.
Frequently Asked Questions (FAQ)
Q: Is this solder suitable for beginners?
A: Yes! The 60/40 tin-lead composition and rosin core flux make it easy to work with, even for those new to soldering.
Q: Does this 60/40 solder for electronics comply with RoHS regulations?
A: No, since it contains lead. For RoHS-compliant applications, consider lead-free alternatives.
Q: What is the shelf life of this 60/40 tin?
A: When stored in a cool, dry place, it can last several years without degradation.
Q: Can this 60 40 tin lead rosin core flux solder be used for plumbing or automotive repairs?
A: No, this is designed for electronics soldering only. To use for plumbing, external compatible aggressive flux is needed. We recommend to order plumbing solder 60/40 in solid wire without flux core, and then apply external flux in the field.
