Abstract

Precision fabrication of stainless steel filters is described. Controlled depth (10 mu m) of metal removal was achieved by an anodic dissolution technique. In addition this technique gave a very smooth surface finish. The limitations encountered in chemical milling methods were largely overcome by this method. Unlike the conventional ECM technique, a plane cathode (instead of a shaped cathode) is used in conjunction with photolithographic masking because by using a shaped cathode alone it is not possible to get the accuracy needed. Photolithographic masking and control of electrochemical parameters ensure accuracy.
