Etching process step by step

Chemical Etching Process: Preparation: The first step in the chemical etching process is creating a proper mask. This can be accomplished by saving the PCB design as a.pdf file format, which most PCB editors allow. Once saved as a .pdf file, the design can be opened in pdf editors such as Foxit Reader [1]

    Step Twelve: Outer Layer Etching. When it comes time to etch the outside layer for the last time, the tin guard is used to help protect the copper during the etching process. Any unwanted copper is removed using the same copper solvent from earlier, with the tin protecting the valued copper of the etching area
