Questions about this product
- How should I store this solder paste and how long does it last?
- You need to keep this solder paste refrigerated between 2 and 10 °C to maintain its quality. Storing it at these cold temperatures gives you a shelf life of six to twelve months. Always let the syringe warm up to room temperature before you start soldering.
- What is the melting point of this solder paste?
- This lead-free alloy has a melting point between 217 and 227 °C. You will need a high-temperature soldering iron or a hot air rework station to reflow it properly. Make sure your equipment can consistently reach and hold these temperatures for a solid joint.
- Can I use this paste for micro-soldering on phones and small electronics?
- Yes, this paste is perfect for high-precision tasks like mobile phone USB socket repairs and SMD rework. The needle tube dispenser lets you apply the paste exactly where you need it on fine-pitch components. It also works great for attaching LEDs to circuit boards where heat management is critical.
