what is flux how many types of flux are there explain with explain
Answers
Flux:
A flux 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.
Types of Flux
For many applications, the flux included in the core of the solder wire is sufficient. However, there are several applications where additional flux is extremely beneficial, such as surface mount soldering and desoldering.
Rosin Flux
Some of the oldest types of flux used is based off pine sap (refined and purified) called rosin. Rosin flux is still used today, but typically is a blend of fluxes to optimize the flux, its performance, and characteristics.
Organic Acid Flux
One of the more common fuxes used is water soluble organic acid (OA) flux. Common weak acids are used in organic acid flux, such as citric, lactic, and stearic acid among others.
Inorganic Acid Flux
A stronger option that organic flux is inorganic flux, which is typically a blend of stronger acids like hydrocloric acid, zinc chloride, and ammonium chloride.
