The RELIFE F-22 Metal Special Flux (55g) is a multi-purpose soldering flux paste widely used in mobile phone repair, PCB work, and general metal soldering. It is formulated with rosin-based active ingredients that help clean and prepare metal surfaces before soldering, ensuring strong and reliable joints.

One of its main functions is to remove oxidation layers from metals like copper, stainless steel, nickel, iron, and galvanized sheets. This improves solder flow (“wetting”) and prevents poor joints or cold solder issues.

The flux has high viscosity, allowing it to stay in place during soldering, especially useful for precision work like smartphone motherboards or small IC components. It also features high insulation resistance and non-conductive properties, making it safe for sensitive electronics.

Additionally, it is designed to be non-corrosive and low-odor, meaning it won’t damage metal surfaces or produce strong fumes during use. It also helps distribute solder evenly by reducing surface tension, resulting in cleaner and more professional solder joints.
