Questions about this product
- How should I store this solder paste?
- Keep it refrigerated to protect the flux and viscosity. Stored cold, shelf life runs about 6 months. Let it warm to room temperature before use so it dispenses and reflows evenly.
- What is this SAC0307 paste best used for?
- It suits precision SMD rework like reattaching charging ports and small connectors. The needle tube lets you place tiny, controlled amounts on fine-pitch pads. The SAC0307 alloy resists thermal fatigue for joints that run warm.
- What temperature does this paste melt and reflow at?
- This lead-free alloy melts around 217 to 227 degrees C. A typical reflow peaks near 240 to 250 degrees C with time above liquidus around 60 to 90 seconds. Plan your hot plate or hot air settings with that headroom in mind.
