BALVER 2220NC
BALVER 2220NC is a cored solder wire designed for repair and rework where a classic leaded solder with built-in flux is required. It belongs to the REL0 class, is halogen-free and no-clean, meaning residues after soldering can be left on the PCB without subsequent cleaning.
The solder wire is based on the Sn63Pb37 alloy, which melts at 183 °C. This makes it suitable for small repairs or standard soldering where a stable and fast soldering process is desired. Balver also states that it provides good wetting and flow in leaded processes and performs well on critical surfaces.
The flux system is flux code 2220 with a flux content of 2.2% w/w. The residues are colorless, and the activator system is designed for low corrosion risk. A temperature of 280–330 °C is recommended for soldering.
Typical applications
- Repair and rework of electronics
- Standard soldering in leaded processes
- Work where no-clean properties are convenient
The product is available in wire diameters from 0.3 mm to 3.5 mm, and spool weights are available in 0.25 kg, 0.5 kg, and 1.0 kg. The documentation refers to IPC-J-STD-004-A and DIN-EN-ISO-9454-1.
