What is Chemical Etching (Photo Chemical Machining, PCM)?

Chemical Etching involves the process of printing an image onto a UV photo sensitive film that is adhered to the metal being etched. Once printed the sheet is developed and prepared for etching. The sheet is then sprayed with a etchant that eats through the material only on the chosen lines that were printed. Once the sheet has been etched all the way through, then all thats left is to remove the UV sensitive film leaving the bare metal and the part required.
