Flux Basics What is Flux

A good flux helps the solder alloy flow on the metal surface. Just as the flux itself spreads onto the surface, the solder alloy must also. A good flux will lower the surface tension between the metal and the molten solder. Before, the surfactant was a wetting agent to help the flux spread. Now the flux is a wetting agent for the solder alloy

Processing Flux::

T he origin of Flux:: goes back to the early days of computer based audio workstations, when the selection of audio software tools for professionals was very limited. We started with the creation of audio processing software, coming from audio engineering, with the core idea to design and create intuitive technically innovative tools for sound engineers, with no compromise of the audio quality.

Flux (metallurgy) Wikipedia

In metallurgy, a flux (derived from Latin fluxus meaning "flow") is a chemical cleaning agent, flowing agent, or purifying agent. Fluxes may have more than one function at a time. They are used in both extractive metallurgy and metal joining. Some of the earliest known fluxes were carbonate of soda, potash, charcoal, coke, borax, lime, lead sulfide and certain minerals containing phosphorus.
