Sintered flux

Sintered flux

Sintered flux refers to a high-quality, high-efficiency, energy-saving and environment-friendly flux. It means that the prepared wet solder is processed into the required particles and calcined at a high temperature of 750~1000 ℃ to form fine particles, which is the sintered solder.
