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. [1] [2] Other names for chemical etching include photo etching, chemical etching, photo chemical etching and photochemical machining. It is ...
186 etched glass at Bankfield Museum. Glass etching, or "French embossing", is a popular technique developed during the mid-1800s that is still widely used in both residential and commercial spaces today. Glass etching comprises the techniques of creating art on the surface of glass by applying acidic, caustic, or abrasive substances.
Etching tanks used to perform Piranha, hydrofluoric acid or RCA clean on 4-inch wafer batches at LAAS technological facility in Toulouse, France. Etching is used in microfabrication to chemically remove layers from the surface of a wafer during manufacturing. Etching is a critically important process module in fabrication, and every wafer ...
ferric chloride may be used for etching copper or zinc plates, whereas nitric acid may be used for etching zinc or steel plates. Typical solutions are 1 part FeCl 3 to 1 part water and 1 part nitric to 3 parts water. The strength of the acid determines the speed of the etching process. The etching process is known as biting (see also spit ...
Etching is a printmaking technique in art. Etching may also refer to: Etching (microfabrication), a process in producing microelectronics; Glass etching, a glass decoration technique; Chemical milling, or industrial etching; Photochemical machining, or photo etching
Photochemical machining (PCM), also known as photochemical milling or photo etching, is a chemical milling process used to fabricate sheet metal components using a photoresist and etchants to corrosively machine away selected areas. This process emerged in the 1960s as an offshoot of the printed circuit board industry.
Acid etching may mean: Glass etching, etching glass; Etching, acid etching of metal surfaces in printing; Printed circuit board § Chemical etching, acid etching in the production of circuit boards; Chemical milling, industrial acid etching
Chemical milling is an example of a specialty process that removes excess material by the use of etching chemicals and masking chemicals. There are many technologies available to cut metal, including: Manual technologies: saw, chisel, shear or snips; Machine technologies: turning, milling, drilling, grinding, sawing
