Solder wire Dedra 31LKAL45 31LKAL45 — brand Dedra, MPN 31LKAL45

Dedra 31LKAL45 solder wire is a branded solder designed for electronics and general metal-joining tasks. It is intended for component assembly, printed circuit board repairs and occasional mechanical soldering where a consistent solder alloy and predictable melting behaviour are required. The product is presented as a ready-to-use wire for hand or station soldering with standard soldering irons and rework equipment.

Advantages

This solder wire offers uniform alloy composition and consistent feed from spools or reels, providing reproducible solder joints and reliable wetting on copper and common PCB surface finishes. Its predictable melting characteristics simplify temperature control during hand soldering and rework. The wire construction minimizes splatter and helps achieve neat joints with good electrical conductivity and mechanical strength for standard electronics applications.

Suitable for

• Through-hole and surface-mount component assembly on PCBs
• Repair and rework of circuit boards and connectors
• General electrical connections and small mechanical soldering tasks

Key specifications

• Form: solder wire suitable for hand soldering and soldering stations
• Alloy: lead-containing or lead-free alloy designed for electronics (check local regulations for lead use)
• Diameter: available in standard wire diameters for fine electronic and general work
• Flux: core flux included for improved solderability and cleaner joints
• Compatibility: suitable for use on copper traces, component leads and common PCB surface finishes

How to use

Prepare work surfaces and secure the board or components to avoid movement during soldering. Heat the soldering iron to the appropriate temperature for the chosen alloy and wire diameter, clean the iron tip, and tin it before use. Apply the iron to the joint to heat the parts evenly, then feed solder wire to the heated joint—allow the molten solder to flow and form a smooth fillet. Remove heat and let the joint cool without disturbance. After soldering, clean residual flux if necessary according to the flux type and safety recommendations.

Usage recommendations

Use appropriate personal protective equipment, maintain adequate ventilation or fume extraction, and follow local regulations regarding lead-containing solders. Select the wire diameter and iron temperature to match component size and thermal sensitivity; smaller diameters and lower heat reduce risk to delicate parts.
