ASAHI WA62J025I
ASAHI WA62J025I is a solder wire with the alloy Sn62/Pb36/Ag2. It is used when soldering components and connections in professional production or service tasks where a wire with built-in flux is required. In this case, it is FC5005, a halogen-free no-clean core flux, allowing soldering to be performed without the usual need for subsequent cleaning.
The flux content is 2.0 ± 0.2 wt%, which is a practical detail as it indicates the amount of flux included in the wire. In practice, this means the solder is designed to provide a controlled and clean soldering process. According to the manufacturer's recommendations, work should be performed at a soldering temperature above 320°C with a soldering time of 1–3 seconds.
After soldering, very little residue remains. The residue is described as clear, slightly yellowish, and dry, and it does not generally require removal. If cleaning is necessary, it can be done with solvent-based cleaning agents.
The wire is available in several dimensions from 0.5 mm to 2.0 mm and is supplied in packaging of 0.25 kg, 0.50 kg, and 1.0 kg. This makes it easier to choose a variant that suits both fine work and more general soldering tasks.

Typical applications
The solder wire is typically used for general manual soldering work where a wire with built-in flux is needed and minimal residue after soldering is desired.
