WebMay 6, 2013 · Photo Chemical Etching is a fabricating process for precision metal components. As an alternative to "conventional" methods, such as stamping, laser, water jet or wire EDM, chemical etching provides an accurate and economical solution for many precision metal applications. WebThere are four primary ways to thin wafers, (1) mechanical grinding, (2) chemical mechanical planarization, (3) wet etching and (4) atmospheric downstream plasma dry chemical etching (ADP DCE). These four techniques fall into two distinct groups: mechanical and etching. harry mahler
