Photo chemical machining, or photo etching, is a fabrication process used in the creation of precision metal parts. Often, it is used as an alternative to conventional processes like stamping, punching, wire EDM, laser cutting and other common machining methods. Currently, photo chemically machined parts are used in a variety of industries, ranging from microelectronics to medical devices and RF & Microwave.

In this guide, you will learn:
