Solder Wire CYNEL Cyna 0.50 mm, 500 g, Sn60Pb40 alloy

CYNEL Cyna solder wire with a 0.50 mm diameter and 500 g spool is a through‑hole and general electronics solder designed for manual and light automated assembly tasks. The Sn60Pb40 alloy provides a defined melting range and reliable wetting behavior suitable for component leads, connectors and wire joints. The medium‑thin 0.5 mm wire diameter offers controlled solder feed for repair, prototyping and production touchups where melt consistency and mechanical strength of joints are required.

Advantages

The Sn60Pb40 composition balances workability and joint reliability with predictable flow and solidification characteristics. The 0.50 mm diameter gives a good compromise between precision and solder availability, enabling accurate placement and reduced bridging on standard through‑hole pads. The 500 g spool ensures extended use in workshops and repair benches without frequent spool changes. Consistent melting behavior supports repeatable solder joints and reduces rework time.

Suitable for

• Through‑hole component soldering on PCB assemblies
• Manual soldering of connectors, wires and cable lugs
• Electronics repair and prototyping
• Small batch assembly and rework tasks

Key specifications

• Alloy: Tin‑Lead alloy with 60% tin / 40% lead
• Diameter: 0.50 mm
• Spool weight: 500 g
• Form: Solid wire for manual soldering
• Typical applications: Electronics through‑hole and general soldering

How to use

Use a clean, appropriately rated soldering iron and apply heat to the joint, not directly to the solder wire. Feed the 0.5 mm solder wire into the heated joint so the alloy melts and flows around the pad and lead. Maintain proper tip temperature and clean the soldering iron tip regularly to ensure good thermal transfer and avoid oxidation. After soldering, allow joints to cool without disturbance to form smooth, shiny connections.

Usage recommendations

For best results, use flux‑cleaning practices appropriate for the flux type on the wire and follow workplace safety measures for lead‑containing solders, including good ventilation and hand hygiene. Select a soldering iron tip size that matches the 0.5 mm wire and the pad dimensions to ensure efficient heat transfer and consistent joint quality.
