Solder Dedra 31L92505 — lead-free solder wire (mpn 31L92505)

Dedra 31L92505 solder wire is a lead-free solder designed for electronic and electrical soldering tasks. Supplied on a roll, this solder wire is intended for manual work with a soldering iron and is suitable for joining electronic components, repairing circuit boards and carrying out general PCB soldering. It is compatible with standard fluxes and typical soldering workflows, providing a standard option for environments where lead-free materials are required.

Advantages

This lead-free solder wire offers a consistent melting behaviour and reliable wetting on common PCB pads and component leads. Its formulation reduces exposure to lead, making it appropriate for electronics manufacturing and repair where lead-free processes are mandated. The roll format ensures controlled dispensing for manual soldering tasks and simple storage between jobs.

Suitable for

• Manual soldering of through-hole and surface-mount electronic components
• Repair and rework of PCBs and electronic assemblies
• Electrical connections and wiring in consumer electronics and small appliances
• Hobbyist and prototyping work requiring lead-free solder

Key specifications

• Lead-free solder alloy composition suitable for electronics
• Supplied as a spool/roll of solder wire for manual dispensing
• Designed for use with a standard electric soldering iron
• Compatible with common rosin and water-soluble flux types
• Intended melting and wetting properties for PCB pads and component leads

How to use

Prepare the work area by securing the PCB or assembly and cleaning the soldering points from oxidation and contaminants. Preheat the soldering iron to an appropriate temperature for lead-free soldering, typically higher than for leaded alloys, and apply flux if necessary. Heat the joint with the iron tip, touch the solder wire to the heated joint (not directly to the iron tip) and allow the solder to flow and wet the surfaces. Remove heat and let the joint cool undisturbed to form a solid connection. Clean residual flux according to the flux type used.

Usage recommendations

For consistent results, use a soldering iron tip sized to the component and pad dimensions, work at a temperature suitable for lead-free alloys, and employ appropriate flux to improve wetting. Ventilate the workspace and follow safety practices for soldering. Store the solder roll in a dry place to prevent contamination and oxidation.
