Flux

Term from Electronics Manufacturing industry explained for recruiters

Flux is a cleaning and protective substance used in electronics manufacturing when joining metal parts together, particularly during soldering. Think of it like a special cleaning agent that helps metals stick together better. When manufacturers solder electronic components onto circuit boards, flux helps remove oxidation (rust-like substances) and ensures strong, reliable connections. It's similar to how you might clean a surface before applying glue to make sure it sticks properly. This term is very important in electronics assembly and manufacturing roles, as proper flux usage directly affects product quality and reliability.
