Flux is a crucial component in the field of electronics soldering, serving multiple essential functions:

Cleaning: Flux effectively removes oxides and impurities from metal surfaces, ensuring a clean area for soldering.

Protection: During the soldering process, flux helps prevent further oxidation by shielding the metal surfaces.

Enhancement: Flux promotes wetting, enabling the molten solder to spread and bond more efficiently and reliably with the metal.

Standards: Quality fluxes comply with international standards like IPC and JIS and may also be environmentally friendly, being lead-free or halogen-free.

The right flux selection and application can significantly improve soldering outcomes, contributing to the reliability and performance of the final electronic product.
