The process of creating designs or patterns on a material (usually metal) by using electrical current to remove material chemically and precisely.
From electro- + etching (from Dutch etsen 'to etch,' from German ätzen). Electroetching modernized the traditional etching process by making it precisely controllable through electrical current.
Electroetching is the foundation of how circuit boards are manufactured—electrical current guides exactly which areas get chemically dissolved away to create the intricate patterns that make your electronics work.
