Solder Tin Wire CYNEL 0.90 mm, 1 kg, Sn60Pb40 alloy

CYNEL solder tin wire with 0.90 mm diameter on a 1 kg spool is a lead-tin alloy product composed of Sn60Pb40 designed for general-purpose electronic soldering. The wire supplies molten solder for through-hole assemblies, hand-soldering of components and wire joints, and is intended for applications where the properties of a Sn60Pb40 alloy are acceptable. The product is presented as a practical spool format for repeated use in repair, prototyping and light manufacturing environments.

Advantages

The Sn60Pb40 composition offers a lower melting range compared with higher-tin alloys, ensuring predictable flow and wetting on common component leads and PCB pads. The 0.90 mm diameter balances ease of feeding and controlled solder amount for manual soldering tasks. The 1 kg spool format reduces the need for frequent replacement in workshops and service benches, and the alloy’s mechanical and electrical characteristics are consistent with traditional leaded soldering practices.

Suitable for

• Through-hole assembly and repair of electronic boards
• Hand-soldering of passive and discrete components
• Wire-to-wire and wire-to-terminal joints
• Prototyping and low-volume production where leaded solder is permitted

Key specifications

• Alloy composition: Tin-lead alloy (60% tin, 40% lead)
• Wire diameter: 0.90 mm
• Spool weight: 1 kg
• Form: Solid solder wire on spool
• Typical use: Manual soldering, rework, and light assembly

How to use

Prepare the workpieces by cleaning pads, leads and contact surfaces to remove oxidation, grease and contaminants. Heat the joint with an appropriate soldering iron or station set to a temperature suitable for Sn60Pb40 alloy, apply the solder wire to the heated joint and allow the molten solder to flow and wet both surfaces before removing heat. Avoid excessive dwell time to prevent thermal damage to components or boards. Allow soldered joints to cool naturally to form a reliable connection. Follow local safety and disposal rules for lead-containing materials.

Usage recommendations

Use adequate ventilation or local extraction when soldering with leaded alloys and wear personal protective equipment as required. Select a soldering tip size and iron temperature appropriate to the 0.90 mm wire and the components being soldered to achieve proper wetting and minimize thermal stress.
