The Etching top 50 is Discovery PatSnap’ annual ranking of the top 50 Most Patent Filings Etching Key Players in the China. Discovery has identified the top key players, startups & unicorns, fast-growings, news entrants in 2022, ranking from differnt perspectives, including patent filing intensity, academic research capability, news media heat. The company list is generated from various data types.
Etching is traditionally the process of using strong acid or mordant to cut into the unprotected parts of a metal surface to create a design in intaglio (incised) in the metal. In modern manufacturing, other chemicals may be used on other types of material. As a method of printmaking, it is, along with engraving, the most important technique for old master prints, and remains in wide use today. In a number of modern variants such as microfabrication etching and photochemical milling it is a crucial technique in much modern technology, including circuit boards.
