Solder Wire FAQ
Q: What's the difference between 60/40 and 63/37 solder wire?
A: The numbers represent the tin/lead ratio. 63/37 is a eutectic alloy that melts at a single temperature (183°C), while 60/40 has a melting range. The 63/37 flows slightly better and is preferred for precision work, while 60/40 is more economical for general use.
Q: How should I store solder wire to maintain its quality?
A: Store solder wire in a cool, dry place away from direct sunlight. Keep it in its original packaging or an airtight container to prevent oxidation. Properly stored solder wire can last for several years without degradation in performance.
Advanced Features
Our solder wire incorporates several premium features:
- Consistent Diameter: Precision-drawn to ±0.02mm tolerance for uniform melting
- Flux Distribution: Evenly distributed flux core for reliable wetting action
- Low Splatter: Special formulation minimizes spattering during soldering
- Clean Residue: Leaves minimal, non-corrosive flux residue that's easy to clean
Application Guidelines
For best results with our solder wire:
- Clean surfaces thoroughly before soldering
- Use appropriate heat settings (300-350°C for leaded, 350-400°C for lead-free)
- Apply solder wire to the joint, not directly to the iron tip
- Allow joints to cool naturally for maximum strength
- Clean flux residue with isopropyl alcohol if required
Solder Wire FAQ Continued
Q: Why does my solder wire sometimes produce smoke during soldering?
A: The smoke comes from the flux core activating and burning off. This is normal but indicates you should work in a well-ventilated area. Using a fume extractor is recommended for frequent soldering work. The amount of smoke varies with flux type - rosin fluxes produce more visible smoke than no-clean formulations.
Industry Compliance
Our solder wire meets or exceeds important industry standards:
- RoHS compliant lead-free options available
- IPC-J-STD-006B compliant for electronic grade solder
- ISO 9001:2015 certified manufacturing
- REACH SVHC compliant
Choosing the Right Solder Wire
Consider these factors when selecting solder wire:
| Application | Recommended Alloy | Recommended Diameter |
|---|---|---|
| Surface mount components | 63/37 or SAC305 | 0.5mm |
| Through-hole components | 60/40 or SAC305 | 0.8-1.0mm |
| Heavy gauge wiring | 60/40 | 1.2mm |
Troubleshooting Common Soldering Issues
When using solder wire, you might encounter:
- Cold joints: Caused by insufficient heat - increase temperature slightly
- Icicle formation: Result of moving joints during cooling - hold steady
- Poor wetting: Often due to dirty surfaces - clean thoroughly before soldering
- Excessive flux residue: Use less solder or switch to low-residue formula
Solder Wire Safety Precautions
Always observe these safety measures when working with solder wire:
- Work in a well-ventilated area
- Use eye protection
- Wash hands after handling leaded solder
- Keep solder wire away from children and pets
- Dispose of waste properly according to local regulations
