Solder Tin Wire CYNEL 0.90 mm, 500 g Sn60Pb40 alloy

CYNEL solder tin wire with 0.90 mm diameter and 500 g spool is a tin–lead alloy wire composed of 60% tin and 40% lead (Sn60Pb40) intended for through-hole and general electronic soldering. The material delivers a predictable melting range and reliable wettability suitable for assembly, repair and prototype work on printed circuit boards and electrical connections. The 0.90 mm core diameter balances ease of feed with sufficient solder volume for joints on larger components and connectors.

Advantages

The Sn60Pb40 composition ensures a stable melting behavior and good wetting on common component leads and copper pads, helping to form consistent solder joints. The 500 g spool provides extended usage between changes, reducing downtime during workshop and production tasks. The 0.90 mm thickness offers an appropriate feed rate for hand soldering with standard irons and for simple automated wire-feed systems.

Suitable for

• Through-hole soldering of resistors, capacitors, headers and connectors
• General repair and rework of consumer electronics and power supplies
• Prototype assembly and bench electronics where leaded solder is acceptable
• Wire soldering and joining of larger gauge conductors

Key specifications

• Alloy composition: 60% tin, 40% lead (Sn60Pb40)
• Wire diameter: 0.90 mm
• Spool weight: 500 g
• Form: solid solder wire
• Typical applications: PCB through-hole joints, electrical connections, general electronics repair

How to use

Prepare the surfaces by cleaning and removing oxidation or contaminants from component leads and PCB pads. Heat the joint with an appropriately sized soldering iron until both the component lead and pad reach soldering temperature, then apply the solder wire to the heated area so the alloy flows and wets the surfaces. Avoid overheating; allow the solder to cool naturally to form a smooth, shiny joint. Use appropriate ventilation and, where required, local fume extraction when soldering with leaded alloys.

Usage recommendations

Use rosin-based flux or flux-core variants compatible with Sn60Pb40 when additional wetting aid is needed, and follow local regulations on leaded solder disposal and handling. For fine-pitch or sensitive surface-mount work, consider using thinner-diameter solder wire or alternative lead-free alloys as appropriate.
