1. CHEMICAL MILLING (CHM) DIP COATING (cotd) Thickness of coating is not uniform –thin at the top thicker at the bottom. This can be corrected by inverting workpiece during next dip Each dip produces a coating between 0.05 and 0.1 mm. Most chemical milling work requires mask thickness from 0.25 to 0.3 mm to ensure sufficient strength.
