The purpose of flux in soldering
Did you know?
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. 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 ...

Webb16 juni 2024 · Since most fluxes must reach and maintain an activation temperature during soldering to ensure complete wetting of the solder joints, the circuit board must pass through a preheating zone before entering the wave trough. The preheating after the flux coating can gradually increase the temperature of the PCB and activate the flux.
Webb11 feb. 2024 · No, soldering flux and solder paste are not the same. Solder paste is a mixture of metal alloy particles and a flux. The purpose of the flux is to help the solder melt easier and create a stronger bond between two items.
