According to the scheme,liquid can be prevented from dripping on the bottom face.

Description

technical field [0001] The invention relates to the field of circuit board production, in particular to the field of circuit board production auxiliary tools. Background technique [0002] Circuit board, also known as printed circuit board, can gather a large number of electrical components together and provide them with electrical connections, and is an essential part of electronic components. At present, most of the circuit board production and processing are made by advanced etching process. First, the electronic board that needs to be preserved, that is, the graphic part of the circuit, is coated with a layer of aluminum tin layer for protection, and then the unnecessary place is etched by corrosion. Erosion, this processing method is etching technology. The etching process is divided into dry etching and wet etching. When wet etching is used, the etching solution still remains on the processed circuit board. During the process of transferring the circuit board to anoth...
