Chemical Machining: Photo Chemical Machining (PCM) is also known as Photo Etching, Photo Chemical Milling, Photofabrication, Chemmilling and Chemical Blanking. Chemical machining is primarily used in the production of thin and decorative parts. Chemical milling is considered a precision process and is most commonly used to machine sheets and foils. Chemical machining is widely used in the electronics and aerospace industries. Common applications of photo chemical machining include integrated circuit lead frames, surface mount paste screens, optical attenuators, encoder disks, jewelry and meshes. Most commonly a photo-tool is produced to the exact geometry to be machined using a laser photo-plotter. The photo-tool selectively exposes a photographic film according to the computer-aided design (CAD) data. Photo-resists are UV light-sensitive polymers. Photo-resists are applied to the metal to be machined as a liquid by dip coating, flowing, roller-coating, or electrophoresis. The coating of the metal sheet with photo-resist sensitizes it. When this sensitized metal is put into the double-sided photo-tool and is exposed to UV light on both sides, an image is etched into the photo-resist. The photo-resist tool is then developed in a liquid formulation to form a durable image on both sides of the metal.
