Ferric Chloride Etching is a general technique used to etch metal, specifically copper and stainless steel. This method involves applying a resist, such as parch or photoresist, to the metal surfaces to identify the areas to be etched. The metal is then submerged in a mixture of ferris chloride, a strong oxidation component that dissolves the exposed metal, making complicated designs and patterns. This process is extensively used in the production of printed circuit boards, decorative products, nameplates, etc. Ferric chloride etching is valuable for its quality, capacity to make fine details, and compatibility with other various metals, making it an adaptable and potent choice for many applications.
