[0002] An integrated circuit is a microelectronic device or component. During the processing of the integrated circuit, it needs to be processed by an etcher. The etcher can be divided into two categories: chemical etcher and electrolytic etcher. In chemical etching, chemical solutions are used to achieve the purpose of etching through chemical reactions. Chemical etcher is a technology that removes materials by chemical reactions or physical impacts. At present, the etching process of circuit boards is generally used. The typical process of printed circuit board processing adopts the "graphic electroplating method", that is, first pre-plating a layer of lead-tin anti-corrosion layer on the copper foil part of the outer layer of the board that needs to be retained, that is, on the graphic part of the circuit, and then the remaining copper foil is corroded by immersing it in the etching solution and waiting for the chemical reaction.

[0003] At present, integrated circuit boards are generally inserted into etching liquid and etched by clamping. Due to the small thickness of the circuit board and the narrow space available for clamping, the traditional clamps that clamp on both sides have the disadvantage of not being firm enough, and strong clamping will easily damage the board. In addition, the clamped circuit board is left stationary in the etching liquid waiting for the chemical reaction, which is slow, and corroded impurities are also likely to remain on the board surface. After etching is completed, when manually removing the circuit board, it is necessary to perform the tedious steps of opening the clamps one by one. Summary of the invention
