WebEtching Definition: a selective removal of material from the surface of a PCB by means of the chemical action of an etchant (or etching agent). Etching usually removes the copper areas which are not desired on the finished PCB. There are two basic ways to remove unwanted copper from copper clad substrates to form electronic circuits: 1. Chemical milling or industrial etching is the subtractive manufacturing process of using baths of temperature-regulated etching chemicals to remove material to create an object with the desired shape. Other names for chemical etching include photo etching, chemical etching, photo chemical etching and photochemical machining. It is mostly used on metals, though other materials …
