Abstract
The sheet metal or substrate materialis constructed by a photo-chemical machining or milling method. In this exemplary process, an etching maskis applied to both sides of the substrateand covers the structure of the flat-shaped member, which is to be uncovered in a subsequent etching step. The maskis formed by coating the substratewith a photoresist and is exposed through a photomask having the desired pattern that is arranged in front of the mask, whereby the photoresist is polymerized or hardened in the covered areas while the other areas are rinsed away after development.
