Solder Wire CYNEL Cyna 0.56 mm 250 g Sn60Pb40

CYNEL Cyna solder wire 0.56 mm, 250 g, alloy Sn60Pb40 is a leaded tin‑lead solder intended for general electronic and electrical soldering. It is supplied as a round wire with a consistent diameter to ensure stable feeding for hand soldering and small automated soldering stations. The Sn60Pb40 composition provides a well‑known melting range and wetting behavior suitable for through‑hole and some surface mount component work, repairs and prototype assembly.

Advantages

The solder wire offers uniform diameter and smooth surface for predictable solder flow and reduced splatter. The Sn60Pb40 alloy provides reliable wetting on common plated copper pads and component leads, while the 0.56 mm diameter balances ease of use for detailed work and sufficient mass for slightly larger joints. The 250 g spool size reduces changeovers in small production or repair environments.

Suitable for

• Hand soldering of electronic circuit boards and components
• Repair and rework of wires, connectors and small assemblies
• Soldering of through‑hole components and general electrical joints
• Small batch or prototype assembly where leaded solder is specified

Key specifications

• Alloy composition: tin‑lead Sn60Pb40
• Wire diameter: 0.56 mm
• Net weight: 250 g
• Form: round solder wire on a spool
• Typical applications: electronics soldering, electrical connections, component repair

How to use

Prepare the work area with adequate ventilation and appropriate personal protective equipment. Clean the soldering surfaces to remove oxidation and contaminants. Heat the joint with a suitable soldering iron or station until the base metals reach soldering temperature, then apply the solder wire to the heated joint so the solder flows and wets both surfaces. Remove the heat once the solder has flowed smoothly and allow the joint to cool without disturbance. For through‑hole work and larger pads, apply slightly more solder; for fine work, feed the wire carefully to control the amount.

Usage recommendations

Use flux‑coated or flux‑core variants if additional flux is required; otherwise apply an appropriate flux to improve wetting. Observe local regulations and workplace safety regarding the use of leaded solders, including proper waste disposal and hygiene measures to limit lead exposure.
