Solder wire Dedra 31L61005, leaded/lead-free not specified, 31L61005

Solder wire Dedra 31L61005 Sn60Pb40 1 mm 50 g with flux core is a flux‑cored tin‑lead alloy wire designed for manual soldering of electronic components and general electrical joints. The Sn60Pb40 composition provides a reliable melting range and consistent solder flow suited for through‑hole components and other leaded assemblies. Supplied in a 50 g spool with a 1 mm diameter, this solder wire is intended for repair, prototyping and small assembly tasks where controlled wetting and easy handling are required.

Advantages

The Sn60Pb40 alloy ensures predictable melting behavior and good mechanical strength of soldered joints. The flux core promotes efficient oxide removal and improves wetting and flow on common component leads and PCB pads. A 1 mm diameter balances heat transfer and accessibility for both fine and slightly larger joints, while the compact 50 g spool is convenient for occasional use and small workshops.

Suitable for

• Repairing through‑hole electronic components
• Prototyping and hobby electronics
• Small electrical assemblies and connector joints
• General soldering tasks on PCBs with leaded components

Key specifications

• Alloy composition: tin‑lead (Sn60Pb40)
• Diameter: 1 mm
• Weight: 50 g spool
• Flux type: flux‑cored wire suitable for manual soldering
• Form: solid wire with internal flux core

How to use

Use with an appropriate temperature‑controlled soldering iron set to the recommended temperature for Sn60Pb40 alloys. Clean component leads and PCB pads before soldering to ensure good wetting. Apply the soldering iron tip to the joint, feed solder wire into the heated area and allow the solder to flow and cover the joint. Remove the solder first, then the iron, and allow the joint to cool undisturbed to form a solid connection. Observe standard safety precautions when working with lead‑containing solder and flux fumes.

Usage recommendations

Work in a well‑ventilated area or use local fume extraction to minimize exposure to flux fumes and lead vapors. Use appropriate personal protective equipment, such as safety glasses and heat‑resistant tools. For applications requiring lead‑free solder, select an alternative alloy; for best results on delicate components, use fine tip irons and lower power settings to avoid thermal damage.
