ASAHI WC63B12 flux-cored solder
ASAHI WC63B12 is a flux-cored solder wire for general soldering work in electronics and other fine assembly. The wire is alloyed in Sn63Pb37, a classic leaded tin-lead alloy familiar to many technicians for precise and rapid soldering.
The core contains CF-10 resin flux, which is described as an activated rosin flux for use in solder wire. In practice, this means the flux helps the solder flow and bond properly to the workpiece, allowing for efficient work without the need to apply separate flux each time. The product's flux classification is ROH1 according to IPC J-STD-004.
When in use, the recommended soldering temperature is 270–350°C, and the typical soldering time is 1–3 seconds. This is well-suited for tasks requiring quick and controlled soldering. The wire is available in a 1.2 mm diameter, among others, and is also available in a 0.50 kg package.
A product video and a datasheet from the manufacturer are also provided for those who wish to see more about the composition and application.

Typical applications
Used for soldering where both tin and flux are required in the same wire, allowing work to be performed quickly and with even wetting.
