## Summary description

GOOBAY 51121 is a lead-free solder wire designed for general electronics soldering with a melting/flow temperature of 217 °C and net weight 12.5 g. Suitable for joining electronic components, small repair tasks and circuit board rework where a lead-free alloy is required. Compact spool for hobbyists and field repairs.

## Long description

GOOBAY 51121 is a lead-free solder wire formulated for general electronics soldering and small repair tasks. The alloy composition is 95.8% tin, 3.5% silver and 0.7% copper with an integrated rosin flux core (2.5% flux content). The solder has a melting/flow temperature of approximately 217 °C and is supplied on a compact 12.5 g spool, making it suitable for hobbyists, field repairs and precise work on small components.
Advantages
This solder wire offers the advantages of a lead-free Sn-Ag-Cu alloy that promotes good wetting and reliable joints on electronic assemblies. The incorporated flux core simplifies soldering by enabling homogeneous flux distribution and reducing the need for additional flux application. The thin-diameter wire allows controlled solder delivery for delicate components, and the alloy composition improves flow behavior and surface quality in lead-free applications.
Suitable for
Soldering on printed circuit boards (PCBs) and through-hole components
Soldering of SMD and DIP components
Repairing cables, headphones, microphones and small consumer electronics
Field repairs and hobby electronics where a compact spool is preferred
Key specifications
Alloy composition: 95.8% tin (Sn), 3.5% silver (Ag), 0.7% copper (Cu)
Flux core content: 2.5% rosin-based flux
Melting/flow temperature: 217 °C
Net weight: 12.5 g per spool
Wire diameter: 1 mm
Lead-free alloy, halogen-free with low smoke emission
How to use
Prepare the surfaces to be soldered by cleaning them from oxidation and contaminants. Use an appropriately tipped soldering iron set to a temperature above the melting/flow point (typically 250–320 °C depending on the joint size and equipment) and heat the joint evenly. Feed the GOOBAY 51121 solder wire to the heated joint, allowing the solder to flow and wet the surfaces. Remove the solder wire and then the soldering iron once a smooth fillet has formed. Allow the joint to cool naturally without disturbance.
Usage recommendations
For best results, work in a well-ventilated area or use local extraction to limit exposure to flux fumes. Use appropriate personal protection such as safety glasses. If no-clean flux residues are a concern for specific high-reliability assemblies, inspect and, if necessary, clean the joint with a suitable solvent or flux remover specified for rosin flux residues.
