Description

Technical Field

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

[0002] The patching of circuit boards refers to the precise placement of patch components on the surface of the circuit board in an automated manner. This is the most critical step in the entire manufacturing process and requires precise equipment and technical support. Before the patching of the circuit board, in order to ensure the quality of the patching, it is necessary to remove dust and other substances on the circuit board as much as possible. The traditional dust removal method generally adopts the spraying method, such as the utility model patent with announcement number CN107051975B. Although this method can remove dust and other substances on the circuit board, these dust and other substances will re-enter the air and will adhere to the subsequent circuit boards and patching equipment. In addition, the patching of the circuit board and the patching equipment are required to be in a dust-free environment as much as possible, so it is necessary to improve the dust removal method of the circuit board.
