[0002] In the prior art, when producing and processing circuit boards, a layer of tin is usually sprayed on the copper surface of the pads on the circuit board to prevent oxidation of the pads. Since tin itself can be soldered, it makes it more convenient to solder components on the circuit board. When tin plating is performed on the copper surface of the pads on the circuit board, the copper surface is first polished to form a rough surface to enhance the adhesion of the tin layer. However, in the prior art, a large amount of dust and impurities are generated during the polishing process. After long-term use, the dust and impurities will clump and adhere to the grinding surface of the polishing block, reducing the roughness of the polishing block and thus greatly reducing the polishing effect of the polishing block on the copper surface of the pads on the circuit board, thereby affecting the subsequent tin plating process and causing the adhesion performance of the tin layer to decrease. At the same time, there are problems such as difficulty in replacing the polishing block and uneven installation in the prior art. SUMMARY
