Solder Wire CYNEL Cyna 2.5 mm 250 g Sn60Pb40 leaded rosin-core

The CYNEL Cyna solder wire is a professional-grade leaded soldering material designed for reliable electrical and electronic connections. With a diameter of 2.5 mm and a total weight of 250 g, this Sn60Pb40 alloy wire is engineered to provide excellent flow and consistent results during manual soldering processes. The integrated rosin core acts as an effective flux, ensuring optimal wetting of surfaces and preventing oxidation during the heating process, which results in strong, durable, and conductive solder joints.

Advantages

This solder wire offers superior performance due to its precise Sn60Pb40 alloy composition, which provides a stable melting point and excellent mechanical strength. The inclusion of a high-quality rosin core simplifies the soldering process by eliminating the need for external flux application in most standard scenarios. Its 2.5 mm thickness is particularly well-suited for larger components and robust electrical connections, ensuring efficient heat transfer and rapid joint formation. The spool design allows for easy handling and storage, making it a practical choice for both professional workshops and hobbyist environments.

Suitable for

• General electronics repair and maintenance
• Soldering electrical components to printed circuit boards
• Wiring and cable termination
• General-purpose metal joining in electrical projects

This solder wire may not be suitable for applications requiring lead-free compliance, such as consumer electronics manufactured under RoHS regulations. Additionally, the 2.5 mm diameter is relatively thick, which may make it less convenient for fine-pitch surface mount technology (SMT) components or delicate micro-soldering tasks where smaller diameters are preferred.

Key specifications

• Alloy composition: Sn60Pb40
• Diameter: 2.5 mm
• Weight: 250 g
• Core type: Rosin-core flux

To use this solder wire, ensure that the surfaces to be joined are clean and free of oxidation or debris. Heat the soldering iron to the appropriate temperature for the Sn60Pb40 alloy. Apply the tip of the iron to the joint area to heat the components, then feed the solder wire directly into the heated joint rather than onto the iron tip. Allow the solder to flow naturally and form a smooth, shiny fillet before removing the heat source and allowing the joint to cool undisturbed.

What to consider before purchase

• Verify that your project does not require lead-free solder compliance
• Ensure the 2.5 mm diameter is appropriate for the size of your components
• Check that your soldering iron is capable of reaching the necessary melting temperature for leaded alloys

For best results, always work in a well-ventilated area to avoid inhaling soldering fumes. Keep the solder wire in a cool, dry place to maintain the integrity of the rosin core.
