What is wet chemical etching?
Silicone and metals can be removed in a controlled etching process using high-purity inorganic acids. Inorganic acids such as nitric, hydrofluoric, hydrochloric, phosphoric, and sulfuric are commonly used for etching. A mixture of acids called mixed acid etchants (MAE) is used for controlled etching containing nitric, hydrofluoric and acetic acid. Eastman EastaPure™ acetic acid is used with the inorganic acid in this mixture.
