The purpose of flux in soldering
In high-temperature metal joining processes (welding, brazing and soldering), flux is a substance that is nearly inert at room temperature, but which becomes strongly reducing at elevated temperatures, preventing oxidation of the base and filler materials. The role of flux is typically dual: dissolving the oxides already present on the metal surface, which facilitates wetting by molten metal, and acting as an oxygen barrier by coating the hot surface, preventing its oxidation. WebbFlux comes from the Latin fluxes, meaning flow. Flux is used as a chemical cleaning and flowing agent when joining metals. This assists solder in adhering properly to the …

To clean surfaces before soldering: This is especially … WebbThe primary purpose of flux in soldering flip chips is the same as with any other component. Fluxing with the proper materials ensures the formation of a strong and reliable metallurgical bond between the IC, solder bump and substrate. A secondary purpose is to provide a “tacky” surface to hold the flip chip in place on its soldering pads ...
WebbReflow soldering is a process in which a solder paste (a sticky mixture of powdered solder and flux) is used to temporarily attach one or thousands of tiny electrical components to their contact pads, after which the entire assembly is subjected to controlled heat. The solder paste reflows in a molten state, creating permanent solder joints.
