Solder Wire CYNEL Cyna 0.25 mm 100 g Sn60Pb40 for electronics repair and assembly

CYNEL Cyna solder wire with a 0.25 mm diameter and 100 g spool is intended for manual soldering of electronic components and printed circuit boards. The alloy composition Sn60Pb40 provides a conventional melting range and wetting behavior characteristic for leaded solders, making this wire suitable for general-purpose electronics repair, prototyping and small-scale assembly when used with an appropriate flux and soldering iron.

Advantages

The 0.25 mm diameter offers precise control for fine-pitch components and detailed PCB work while the 100 g spool gives enough material for multiple repair and assembly tasks. The Sn60Pb40 alloy provides predictable flow and reliable solder joints on common component leads and pad surfaces. This wire is compatible with standard soldering irons and is intended for use with flux to ensure proper wetting and reduced oxidation during the soldering process.

Suitable for

• Repair and rework of electronic devices and circuit boards
• Prototype assembly and hobby electronics
• Soldering through-hole and many surface-mount components with careful temperature control
• General-purpose tasks requiring a conventional leaded solder

Key specifications

• Alloy: Tin-Lead, nominal composition Sn60Pb40
• Wire diameter: 0.25 mm
• Net weight: 100 g
• Form: solid wire on a spool for manual soldering
• Typical application: electronics soldering and PCB assembly

How to use

Prepare the work area, clean component leads and PCB pads to remove dirt and oxidation. Secure the board and components, apply appropriate rosin or activated flux if the solder wire does not contain flux core, and heat the joint with a soldering iron set to a temperature suitable for Sn60Pb40 alloy. Feed the solder wire to the heated joint, allowing it to flow and wet both surfaces; remove heat and allow the joint to cool without disturbance to form a solid connection. Follow safety precautions for lead-containing materials, including good ventilation, personal protective equipment, and proper disposal of flux residues and scrap solder.

Usage recommendations

Use temperature control and a fine soldering tip for precise work at 0.25 mm diameter; if flux-core wire is not used, apply an appropriate flux to improve wetting. Observe local regulations and best practices for handling and disposing of lead-containing solder and residues.
