When it comes to reliable soldering in electronics manufacturing, the choice of solder wire can make or break the quality of your final product. At XF Solder, a professional Tin Wire Chinese Factory, we understand the demands of modern circuit board assembly. Our Resin Core Tin Wire Sn50Pb50 in a 250g spool with a 1.6mm diameter is engineered to deliver consistent, high-quality solder joints at a competitive price point.
This product introduction will walk you through every aspect of this Tin Wire Sn50Pb50 — from its composition and performance characteristics to its applications, packaging, and why it stands out as a cost-effective solution for businesses of all sizes. Whether you are a small repair shop or a large-scale manufacturer, this Resin Core Tin Wire 50 50 is designed to meet your soldering needs with precision and reliability.
The Tin Wire Sn50Pb50 refers to a solder alloy composed of 50% tin (Sn) and 50% lead (Pb). This balanced composition is one of the most widely used solders in the electronics industry, particularly for through-hole and general-purpose soldering applications. The eutectic-like behavior of the 50/50 alloy provides a relatively low melting point of approximately 183°C–190°C, making it easy to work with and suitable for a broad range of soldering temperatures.
The Resin Core Tin Wire Sn50Pb50 features a flux core made from refined rosin (resin). This core serves a critical function: it cleans the metal surfaces during soldering, removes oxidation, and promotes excellent wetting and adhesion. The result is a smooth, shiny solder joint with minimal defects. The resin core also eliminates the need for separate flux application in many cases, streamlining your workflow and reducing material costs.
Melting Point: Approximately 183°C–190°C
Density: ~8.9 g/cm³
Tensile Strength: Moderate, suitable for general electronics
Electrical Conductivity: Excellent, ensuring reliable connections
Flux Content: Typically 1.5%–2.5% rosin core
These properties make the Tin Wire Sn50Pb50 250g spool an excellent choice for both hand soldering and automated soldering processes.
One of the standout features of the Resin Core Tin Wire 50 50 is its uniform flux distribution. The manufacturing process at XF Solder ensures that the rosin core is evenly distributed throughout the length of the wire. This consistency means every solder joint receives the right amount of flux, reducing the risk of cold joints, bridging, and other common soldering defects.
The Resin Core Tin Wire Sn50Pb50 exhibits excellent wetting properties, allowing the molten solder to flow smoothly across copper pads and component leads. This is particularly important for Tin Wire Sn50Pb50 for Circuit Boards, where dense component layouts and fine pitch connections demand precise solder flow. The resin core activates at soldering temperatures, ensuring optimal surface preparation without leaving excessive residue.
Unlike some aggressive flux formulations, the rosin core in this Resin Core Tin Wire 50 50 leaves minimal residue that is non-corrosive and easy to clean if desired. For many applications, the residue can be left on the board without affecting performance, saving time and cleaning costs in the production process.
The Tin Wire Sn50Pb50 1.6mm diameter is a versatile size that balances control and productivity. A 1.6mm wire is thick enough to deliver solder quickly for larger joints, yet thin enough for precise application on standard through-hole components. This diameter is particularly well-suited for:
Through-hole component soldering
General PCB assembly
Repair and rework operations
Prototyping and small-batch production
The Tin Wire 50 50 1.6mm diameter works well with a wide range of soldering irons and stations. Whether you are using a 30W pencil iron or a temperature-controlled soldering station, this wire diameter provides consistent feed and melt characteristics. It is also compatible with automated soldering equipment, making it a flexible choice for different production setups.
When it comes to Tin Wire 50 50 for Circuit Boards, the 1.6mm diameter offers an ideal balance. It provides sufficient solder volume for typical through-hole joints while allowing operators to control the amount of solder applied. This reduces waste and ensures neat, professional-looking joints.
The Tin Wire Sn50Pb50 250g spool is designed for convenience and efficiency. The 250-gram format is large enough for extended production runs yet compact enough for easy storage and handling. The spool is compatible with standard solder wire dispensers and feeders, ensuring smooth wire feed without tangling or kinking.

The Tin Wire Sn50Pb50 for Circuit Boards is particularly well-suited for through-hole component assembly. Its moderate melting point and excellent flow characteristics make it easy to form reliable solder joints around component leads and PCB pads. This is especially important for components that require strong mechanical connections, such as connectors, switches, and power components.
The Resin Core Tin Wire Sn50Pb50 is also an excellent choice for repair and rework operations. The built-in flux core makes it easy to reflow existing joints and add solder where needed. The 1.6mm diameter provides good control for precise rework on densely populated boards.
To get the most out of your Tin Wire Sn50Pb50 1.6mm, follow these best practices:
Maintain proper tip temperature: Set your soldering iron to 300°C–350°C for optimal flow.
Clean surfaces before soldering: Remove oxidation and contaminants from pads and leads.
Use adequate ventilation: Solder fumes should be extracted to ensure operator safety.
Apply solder efficiently: Feed solder to the joint, not the iron tip, for best results.
Inspect joints: Check for shiny, smooth joints and rework any that appear dull or incomplete.
The Tin Wire Sn50Pb50 alloy has a melting range of approximately 183°C to 190°C. This relatively low melting point makes it easy to work with and suitable for a wide range of soldering applications. It is important to note that the exact melting behavior depends on the heating rate and the specific soldering conditions. For most hand soldering applications, a soldering iron temperature of 300°C–350°C is recommended to ensure proper flow and wetting.
The Resin Core Tin Wire 50 50 is suitable for a wide variety of circuit boards, including single-sided, double-sided, and multilayer PCBs. However, it is important to consider the specific requirements of your application. For example, if you are soldering components that are sensitive to heat, you may need to use a lower soldering temperature and shorter dwell time. Additionally, for applications that require no-clean flux or lead-free compliance, alternative products may be more appropriate. Our team at XF Solder can help you select the right product for your needs.
Proper storage of Tin Wire Sn50Pb50 250g spools is important to maintain product quality. Store the spools in a cool, dry environment away from direct sunlight and moisture. The ideal storage temperature is between 10°C and 30°C with relative humidity below 60%. Keep the spools in their original packaging until ready for use to protect the wire from dust and oxidation. If stored properly, the solder wire has a shelf life of approximately two years.
Yes, the Tin Wire 50 50 1.6mm diameter is compatible with many automated soldering systems, including robotic soldering stations and wire feeders. The consistent diameter and uniform flux core ensure reliable feeding and consistent solder deposition. However, it is important to verify compatibility with your specific equipment and adjust parameters such as feed rate and soldering temperature accordingly. Our technical team can provide guidance on integrating our products into your automated processes.
