If you’re part of the electronics manufacturing industry, then you’re probably already familiar with flux. However, if you’re not and have no idea what we’re talking about, this article is for you! Flux is a commonly used material for several different industries and applications. Here, we will focus solely on solder flux.
Simplified
Derived from the Latin word Fluxus, flux means “flow.” This chemical cleaning, or flowing agent, is also referred to as a purifying agent. Flux wears many hats because it provides multiple functions at once. The primary function is to prevent oxidation while joining metals.
Cleaning agents
As a cleaning agent, flux enables soldering by removing oxidation from the metals to be joined. It then seals out the air to prevent further oxidation from occurring. The third function of soldering flux is the facilitation of amalgamation to improve wetting characteristics of the liquid solder.
Variations
In high-temperature metal joining processes, flux enables the solder to adhere to a clean metal surface. However, there are several different types of flux. Choosing the right flux for your job will be dependent on the metals being utilized. For example, if your soldering stainless steel a solder flux that has a solution of zinc chloride in hydrochloric acid will work best. Whereas magnesium alloys can be worked with molten acetamide.
Components
Regardless of the variation, flux consists of the four following components:
In other words, flux removes oxidations, aids in heat transfer, cleans and prepares the joint to accept the solder, and promotes even solder flow.
