Definitions for "Photoetching"
An etching process in which the resist is applied to the metals surface by photographic means.
An intaglio process in which the etching plate is coated with a light-sensitive acid-resistant ground and exposed, through a dot screen, to a photographic image. A "negative" resist dissolves in the areas that are exposed to light, while hardening in areas not exposed to it. Thus pits are etched and ink is held in the areas that appear light in the photographic image. A positive resist dissolves where it is not exposed to light.
A process that uses chemical or machine etching to remove material from a metal. This produces small parts with much higher detail than can be obtained through injection mould ed plastic. Photo etch parts are common after-market products.
Chemical process of removing unwanted material in producing printed circuit boards.
