Solder Wire CYNEL CYN-0.90/100 — CYNEL leaded solder wire 0.90 mm, 100 g spool

CYNEL CYN-0.90/100 leaded solder wire is supplied on a 100 g spool with a 0.90 mm diameter. It is intended for manual soldering of electronic components, wires and small metal parts where a thin, controllable solder is required. The spool format provides steady feed during use and helps maintain consistent solder joints in repair, assembly and hobby electronics tasks.

Advantages

The fine 0.90 mm diameter enables precise application on small pads and narrow traces while reducing excess solder. Supplied on a compact 100 g spool, the wire offers convenient storage and steady unwinding for manual soldering. As a leaded formulation, it provides reliable wetting and good joint strength, simplifying solder flow and improving mechanical connection between parts.

Suitable for

• Repair and rework of electronic circuit boards and components
• Soldering of small wires and connectors in appliances and devices
• Prototype assembly and DIY electronics projects
• Hobbyist model electronics and precision soldering tasks

Key specifications

• Wire diameter: 0.90 mm
• Spool weight: 100 g
• Composition: leaded solder (tin-lead formulation)
• Form: continuous wire on spool for manual feed

How to use

Trim the required length of solder wire from the spool and position the soldering iron tip to heat the joint area until both surfaces reach wetting temperature. Feed the solder wire to the heated joint, allowing it to flow and form a smooth fillet; withdraw the wire first and then remove the iron to avoid cold joints. Use appropriate soldering iron temperature and a compatible flux or flux-core if necessary to ensure good wetting and clean joints. Store the spool in a dry place when not in use to prevent contamination.

Usage recommendations

For most small electronic components and board work, use a soldering iron temperature in the typical range for leaded solders and apply only enough solder to form a reliable joint. Use proper ventilation when soldering and follow safety guidelines for handling leaded materials, including hand hygiene and separation from food preparation areas.
