Solder Wire CYNEL CYN-1.20/100 — CYNEL 1.20 mm diameter, 100 g spool

CYNEL solder wire CYN-1.20/100 is a 1.20 mm diameter, 100 g spool intended for manual soldering and repair tasks. It is designed for general electronics and electrical joining, offering a steady wire feed suitable for through-hole components, wire connections and basic surface-mount work. The spool format keeps the wire organised and reduces tangling during repetitive soldering operations.

Advantages

The 1.20 mm diameter provides good thermal mass for reliably forming solder joints on larger leads and wire connections while remaining easy to control for hand soldering. The 100 g spool balances quantity and storage convenience for hobby and workshop use. Consistent diameter and spool winding ensure predictable feed and minimised interruptions during assembly or repair. The product is compatible with standard soldering irons used in electronics maintenance.

Suitable for

• Soldering through-hole electronic components
• Repairing wire-to-wire and wire-to-terminal connections
• General electrical joining in small appliances and devices
• Hobby electronics, prototyping and education tasks

Key specifications

• Wire diameter: 1.20 mm
• Spool weight: 100 g
• Product form: solid solder wire on spool
• Intended application: manual soldering and repair
• Suitable for: through-hole components, basic surface work, wire joints

How to use

Prepare the workpiece by cleaning component leads and pads to remove oxidation and contaminants. Heat the joint with a suitable soldering iron until the metal reaches wetting temperature, then apply the solder wire to the heated area rather than to the iron tip to achieve a proper solder fillet. Feed the 1.20 mm wire steadily to control the amount of solder deposited; allow the joint to cool without disturbance to form a reliable connection. Trim excess leads and inspect the joint for continuity and mechanical strength.

Usage recommendations

For best results use a soldering iron with adequate power for the workpiece size (typically 30–60 W for general electronics) and appropriate tip geometry to transfer heat efficiently. Ensure proper ventilation when soldering and consider using flux or flux-core variants suitable for electronics if additional wetting or cleaning is required.
