Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a high-performance chemical pump. Background Art

[0002] As the chip carrier of integrated circuits, the lead frame is a key structural component that uses bonding materials (gold wire, aluminum wire, copper wire) to achieve electrical connection between the internal circuit lead ends of the chip and the external leads to form an electrical circuit. It serves as a bridge to connect to external wires. Lead frames are required in most semiconductor integrated blocks and are an important basic material in the electronic information industry.

[0003] High-density integrated circuit lead frames are basic components for manufacturing integrated circuit semiconductor components. In order to meet the needs of manufacturing integrated circuit semiconductor components, local areas on the surface of integrated circuit lead frames need to be electroplated with metal silver or nickel-palladium-gold. Electroplating refers to a surface processing method in which the cations of the pre-plated metal in the plating solution are deposited on the surface of the base metal through electrolysis in a salt solution containing pre-plated metal, with the base metal to be plated as the cathode, to form a coating. During electroplating, the plating metal or other insoluble material acts as the anode, and the workpiece to be plated acts as the cathode. The cations of the plating metal are reduced on the surface of the workpiece to be plated to form a coating.

[0004] Whether it is electroplating or the cleaning steps before and after electroplating, chemical pumps used to transport liquids (chemical solutions or cleaning fluids) are involved, which have complex structures and are inconvenient to maintain. Furthermore, the water inlet of the existing chemical pump is located underwater, and the liquid is transported upward. There is a right-angle turn at the water inlet, which has a large impact and resistance, greatly reducing the water flow speed, thereby reducing the smoothness of the water flow and increasing energy consumption.
