Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a PCB circuit board dust removal device. Background Art

[0002] PCB circuit board is a board with printed wires. Its main function is to reduce the space occupied by wires and organize the wires in a clear layout. In the manufacturing process of circuit boards, especially in the welding and assembly process, a lot of dust, solder residues and other impurities will be generated. If these impurities remain on the circuit board, it will cause circuit short circuit, poor electrical connection or performance problems of terminal equipment. In order to avoid the influence of dust and impurities on the circuit board, the circuit board is dusted after welding and assembly. At present, when removing dust from the circuit board, most of them will install high-pressure nozzles on the upper side of the circuit board conveyor belt, and use the compressed air sprayed by the high-pressure nozzles to remove dust from the circuit board. Although this dust removal method can remove some dust and active solder residues, some dust and solder residues will adhere to the circuit board during welding, resulting in incomplete dust removal of the circuit board. The residual solder residues and dust on the circuit board will also have a certain impact on the circuit board. Utility Model Content
