In electronic products, the research and development, production and processing of electronic PCB boards are the top priorities. PCB boards are important electronic components, the support of electronic components, and the provider of electrical connections for electronic components. Gold fingers are important components on PCB boards. Gold fingers refer to the gold-plated conductive contacts on PCB boards, which are mainly connected to other electronic devices or other PCB boards. They are one of the important parts of electronic equipment because gold fingers are responsible for transmitting signals and power and ensuring the normal operation of the equipment.

[0003] During the processing of the gold finger of the PCB board, debris and dust will remain on the surface. The cleanliness of the gold finger will directly affect the subsequent process of the product. In order to ensure its cleanliness, the current conventional practice is to clean the product. The existing cleaning method is that the staff directly holds the air gun nozzle and cleans in one direction. This cleaning method will cause foreign matter to diffuse in the air, and dust will fall to cause secondary pollution. In addition, the high-pressure air gun has a loud noise, which will cause noise pollution. There is no dust collection device, and foreign matter cannot be quickly collected to a fixed device.
