Solder wire Proline 60330, 100 g spool, leaded electronics solder

Proline 60330 is a 100 g spool of leaded electronics solder wire formulated for general electronic and electrical soldering. The wire composition with 60% tin and 40% lead and a flux core provides a balance of wettability and strength suitable for joining components, repairing printed circuit boards and performing small-scale soldering tasks. The compact spool design keeps the wire organized and convenient to use with a soldering iron and appropriate flux when additional cleaning or activation is required.

Advantages

This solder wire offers consistent melting behavior and predictable flow thanks to the Sn60 Pb40 alloy and a low-percentage rosin-based flux core. The composition supports strong metallic joints with good mechanical and electrical conductivity. Its spool format is compact for bench use or transport, and the wire diameter is optimized for precision work on small electronic components and pads. The product is intended for both hobby and professional use where traditional leaded solder is acceptable.

Suitable for

• Soldering and rework of through-hole and some small surface-mount electronic components
• Repair and maintenance of circuit boards and electronic assemblies
• DIY electronics projects, prototyping and hobbyist assemblies
• General electrical connections where leaded solder is appropriate

Key specifications

• Alloy composition: 60% tin (Sn) / 40% lead (Pb)
• Flux content: approximately 2.5% rosin-based flux core
• Net weight: 100 g on a compact spool
• Form: solder wire with internal flux core suitable for hand soldering
• Typical use temperature range: suitable for conventional soldering iron temperatures used in electronics

How to use

Prepare the workpiece by cleaning the component leads and PCB pads to remove oxidation and contaminants. Set the soldering iron to an appropriate temperature for Sn60Pb40 solder and let it stabilize. Apply heat to the joint, then feed the solder wire so the flux core activates and the solder flows to wet both surfaces. Remove the solder wire and then the iron, allowing the joint to cool undisturbed to form a solid connection. If additional flux or cleaning is needed, apply suitable flux or use isopropyl alcohol and a brush to remove residues.

Usage recommendations

Observe safety and local regulations when working with leaded solder: use adequate ventilation, avoid inhaling fumes, wear protective equipment if necessary, and wash hands after handling. Dispose of solder waste and contaminated materials according to local hazardous-waste guidelines.
