WebFeb 8, 2024 · In the PCB industry, Cu is the most commonly used metal for circuit line and pad materials. In this study the etching behavior of Cu in two different cases. First, the … Electroetching is a metal etching process that involves the use of a solution of an electrolyte, an anode, and a cathode. The metal piece to be etched is connected to the positive pole of a source of direct electric current. A piece of the same metal is connected to the negative pole of the direct current source and is called the cathode. In order to reduce unwanted electrochemical effects, the anode and the cathode should be of th…
