Description

Technical Field

[0001] The utility model relates to the technical field of PCB board manufacturing equipment, in particular to an automatic exhaust device for a gold immersion filtering circulation system. Background Art

[0002] The immersion gold process is to deposit a nickel-gold coating with stable color, good brightness, smooth coating and good solderability on the surface of the printed circuit. Compared with other processes, the products prepared by the immersion gold process have the advantages of good color, good heat dissipation and good stability. However, a large amount of wastewater will be generated in the process of immersion gold plating. The wastewater contains many types of highly toxic substances, which are very harmful. It needs to be filtered before it can be discharged, and a large amount of waste gas will be generated during the treatment process.

[0003] However, the existing exhaust gas emissions are not regulated, and the exhaust needs are often achieved through exhaust pipes. In some cases where it is necessary to maintain a closed state or a certain pressure, a structure that can achieve automatic exhaust is required. Utility Model Content
