Metal Acid Etching Terms
– A
substance that, when dissolved in water, forms a solution with a pH of
less than seven.
– Lines that are
partially etched into the surface of the metal, which aid in the bending
of the part in a subsequent operation.
– The process of heating
a developed photoresist image until the resist coating becomes chemically
resistant.
– A term originally
used to refer to the process of photo chemical machining (PCM).
– A process
in which ferric chloride acid is regenerated to maintain high quality
acid for the etching process.
– The dipping, rolling,
spraying, laminating, spinning, printing or flowing of the substrate surface
layer of a photoresist material in order to cover it with a resist.
– A photographic
process in which an image is transferred from one substrate to another.
– The subjection
of a substrate surface to high temperatures or the pickling process in
order to improve photoresistant adhesion.
– Photoresist
in the form of rolled sheet laminate.
– Designing
artwork for parts to be photochemically machined so that all shapes are
outlined with a controlled line to be etched.
– An acid used to dissolve
a layer of metal to form the component.
– A series of etched parts
that are tagged into a frame. Blanks usually have several frets etched
into them.
– Non-metallic elements
fluorine, chlorine, bromine and iodine.
– An image etched/sunk
into the surface of a piece.
– An electrically charged
atom or group of atoms, the electrical charge of which results from a
neutral atom or group of atoms losing or gaining one or more electrons.
– A photoresist
applied to the substrate by dipping, roller coating or spraying.
– A device that receives
optical power and changes it into an electrical signal.
– A material that,
when applied to any of a variety of substances, becomes sensitive to portions
of the electromagnetic spectrum and, when properly exposed and developed,
masks a portion of the material.
– The rate
of response of a photographic material to a particular range of the electromagnetic
spectrum.
– A structure that
underlies and supports or forms base material on which coatings are applied.
– Invisible
electromagnetic radiation.
