Chemical etching is a method of engraving that uses a high-pressure high-temperature chemical spray to remove material to create a permanent etched image in metal. A mask or resist is applied to the surface of the material and is selectively removed, exposing the metal, to create the desired image Wet chemical etching is particularly important for microelectronics industry for patterning of integrated circuit, MEMS devices, optoelectronic and pressure sensors. Wet etching processes use solution based (wet) etchants, where the substrate to be etched is immersed in a controlled flow of etchant Chemical etching is also precise enough to make apertures for optical applications, and encoder disks with slots that are wider than the thickness of the material. Very small battery springs and contacts, fine screens and webs, and small covers and step lids can be produced, as can custom thin metal parts per the specifications from the customer Controlled Chemical Plasma Etching for Advanced Technology Applications Page 1 INTRODUCTION .

The quality and permanency of etched metal make it an ideal solution for a wealth of applications. Chemical The process of chemical etching is across an entire sheet of metal: a stencil in the form of a photo-resist coating is applied to the metal and then the etchant is sprayed on which dissolves the unwanted metal and leaves the part with the etchant on it. For this reason it means that unlike other etching methods that can only work on one section.
