Etchants
Etchants are chemical solutions used to selectively remove material from a substrate. They are commonly used in processes such as etching, cleaning, and surface preparation in various industries including microelectronics, metalworking, and materials science. Etchants can be acidic, alkaline, or neutral in nature, and their composition is tailored to the specific material being removed. The choice of etchant is crucial in achieving precise and controlled material removal without damaging the surrounding areas.
