There are multiple receiving frames 131, which is conducive to increasing the number of workpieces 2 clamped at one time, so as to improve the efficiency of electrochemical etching.
[0088] The above are only specific implementation methods of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be included in the disclosure scope of the present application.
