[0019] In the following, the present invention will be described with reference to the accompanying drawings: a system and method for electrochemical processing of a micropit array based on a magnetic PDMS mask includes the following steps:
[0020] a. Make cathode tool 1 and clamp 5. The cathode tool 1 has a uniform group slit structure, the diameter of the liquid inlet of the clamp is 20mm, and two liquid outlets are set on the lower surface of the cathode tool, the diameter is 1mm;
[0021] b. Make a magnetic PDMS mask 2 with an array of through holes, such as Figure 5 ;
[0022] c. Stick the magnetic PDMS mask 2 on the upper surface of the anode workpiece 3, the permanent magnet 4 is close to the lower surface of the anode workpiece, and clamp the cathode tool 1 and the anode workpiece 3 together with the clamp 5, wherein the cathode tool 1 and the magnetic PDMS mask The distance of mold 2 is 15mm;
[0023] d. The anode workpiece 3 and the cathode tool 4 are respectively connect...
