Solder wire Proline 60327, brand Proline, 100 g spool

Solder wire Proline 60327 is a 100 g spool of Sn60 Pb40 alloy solder with 2.5% flux core, intended for general electronics repair and precise soldering tasks. Produced by Proline, this solder wire is formulated for joining electronic components, wires and printed circuit boards where a compact, easy-to-handle spool is preferred. The alloy composition and low-flux content provide stable wetting and predictable joint formation for routine electronics work.

Advantages

The Sn60 Pb40 alloy offers reliable mechanical strength and good electrical conductivity for conventional electronic connections. The 2.5% flux core aids solder flow and reduces the need for separate flux application, supporting cleaner joints and fewer cold solder occurrences. The 100 g spool format is convenient for hobbyists and technicians who require a portable, modest supply without excessive storage bulk.

Suitable for

• Soldering through-hole components on printed circuit boards
• Repairing wires and connectors in consumer electronics
• Hobby electronics, model making and DIY projects
• Small-scale professional maintenance and assembly tasks

Key specifications

• Alloy composition: tin-lead Sn60/Pb40
• Flux content: approximately 2.5% core flux
• Spool weight: 100 g
• Wire form factor: continuous reel suitable for manual soldering
• Designed for use with standard soldering irons and stations

How to use

Use a clean, temperature-controlled soldering iron set to an appropriate temperature for Sn60Pb40 solder (typically around 320–350 °C, adjusted according to tip size and component sensitivity). Ensure component leads and PCB pads are free of oxidation and contaminants before applying heat. Touch the soldering iron tip to the joint to heat both surfaces, then feed the solder wire so it melts and flows into the connection. Withdraw the solder wire and iron once adequate solder has formed, and allow the joint to cool undisturbed to form a solid connection.

Usage recommendations

Store the solder spool in a dry environment and keep it away from excessive heat or direct sunlight. Use appropriate ventilation or fume extraction when soldering to avoid inhaling flux fumes. For work on sensitive components, verify temperature limits and consider using ESD precautions and temperature-controlled tips to reduce thermal stress.
