## Summary description

Leaded solder wire CYNEL Cyna, 2.5 mm diameter, 250 g spool, alloy Sn60Pb40. Designed for general electronics and electrical repairs, component soldering and rework. Rosin-core formulation provides flux for improved wetting and reliable joints on copper and common PCB finishes. Suitable for hand soldering with soldering irons in workshops and repair tasks.

## Long description

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.
