Abstract
PURPOSE: To improve etching accuracy by forming an anodic oxidation film as a masking material on the non-etching parts of a metal base material and selectively etching the non-anodic oxidation parts with the specific etching solution.
CONSTITUTION: Screen-printing ink using epoxy resin or the like as its vehicle is printed on the required etching portions of a substrate such as of Al or other to form a synthetic resin film. Next, an anodic oxidation film is formed on the exposed surface portions of the substrate, after which hole sealing is perfomed. Next, the synthetic resin film, etc. is removed with a thinner or the like and the substrate is dipped in an etching solution containing FeCl3 or other which preferentially etch the substrate as compared to the anodic oxidation film to selectively etch the non- anodic oxidation portions. This method enables etching of a uniform depth to be performed without any damages of the non-etching part even with the substrate of intricate shapes, thereby enabling parts for electronic circuits, etc. of superior characteristics to be obtained.
