Photo Etching

Differentiated TOTAL SOLUTION TECHNOLOGY
We provide various services based on 4 core technologies.

Overview

Photo etching involves photolithography and photo etching technology, and is used in various industrial fields including accurate electronic parts, semi-conductors, displays, automobiles, and FA. Youngjin Astech Co.,Ltd . manufactures and supplies highly precise parts made of various materials.

Photolithography is a technology which applies photosensitizer onto plates and develops it through photo masks in order to form micro patterns and applies photo-etching. It specifically refers to the technology that etching selectively onto the desired patterns.
