Solder Wire Mojeledy Cyna 0.50 mm 100 g Sn60Pb40 with 2.5% flux (SW26/3/2.5%)

Solder wire Mojeledy Cyna 0.50 mm 100 g Sn60Pb40 with 2.5% flux core is a general-purpose solder designed for through-hole and small-scale electronics assembly, repair and prototyping. The 0.50 mm diameter offers a balance between control and flow for work on PCB pads, component leads and wire joints. The alloy composition of 60% tin and 40% lead provides a reliable melting profile and good wetting on copper surfaces where Sn60Pb40 is acceptable.

Advantages

The 0.50 mm diameter allows precise application without frequent feeding, while the 100 g spool provides a compact amount for workshop use. The Sn60Pb40 alloy gives predictable soldering behavior and strong mechanical joints. An internal flux core of 2.5% improves oxide removal and solder flow, reducing the need for additional flux on common copper pads and component leads.

Suitable for

• Through-hole soldering on printed circuit boards
• Repair and rework of electronic assemblies and wire joints
• Hobbyist and prototyping tasks requiring a 0.50 mm solder wire
• Soldering copper pads, component leads and tinned wires

Key specifications

• Alloy composition: 60% tin (Sn), 40% lead (Pb)
• Flux core content: 2.5% (rosin-based core)
• Wire diameter: 0.50 mm
• Net weight: 100 g
• Form: flux-cored solder wire on spool

How to use

Use a temperature-controlled soldering iron set to an appropriate temperature for Sn60Pb40 alloy (typically around 320–360 °C depending on tip size and heating characteristics). Clean the joint area to remove oils and oxidation, then apply the soldering iron tip to heat the pad and component lead simultaneously. Feed the Mojeledy Cyna 0.50 mm solder wire into the heated joint until solder flows and forms a smooth fillet, then remove the solder wire and iron and allow the joint to cool naturally. If excess flux residue is present, clean with suitable flux remover or isopropyl alcohol when the assembly has cooled.

Usage recommendations

Follow industry safety practices when working with leaded solder: use local exhaust ventilation, wash hands after handling, and avoid food contact in the work area. Select a soldering iron tip size and temperature appropriate to the component size to prevent thermal damage. For electronics intended for lead-free compliance, choose a lead-free solder alternative instead of Sn60Pb40.
