Questions about this product
- Is this solder good for electronics and PCB work?
- Yes, that's exactly what it's made for. The Sn99.3 Cu0.7 alloy with rosin core flux wets fast and gives clean, strong joints. It works well for soldering components on boards, fixing cables, and building prototypes.
- Which wire diameter should I pick for my project?
- It comes in seven sizes from 0.5mm up to 2.0mm. Choose 0.5mm for fine PCB pads and small surface-mount parts. Go thicker, toward 2.0mm, when you need to fill bigger joints fast. The spool holds 50 grams.
- What temperature does this lead-free solder melt at?
- It melts at about 227 degrees C, which is the standard point for this tin-copper alloy. That runs a bit hotter than old leaded solder, so set your iron higher to flow it cleanly. The built-in 2.2 percent rosin flux helps it wet smoothly.
