Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing devices, in particular to a circuit board immersion processing device. Background Art

[0002] A circuit board immersion treatment device is a device used to clean and process circuit boards. It usually includes an immersion tank, a spray system, a circulation filtration system and other components. The immersion tank is the part used to place the circuit board, which can be filled with cleaning fluid. Common cleaning fluids include deionized water, solvents or acid-base solutions, etc., which are used to remove dirt, grease and electronic component solder slag from the surface of the circuit board. The spray system is usually located above the immersion tank and is used to spray the cleaning fluid onto the surface of the circuit board to increase the cleaning effect. The circulation filtration system is used to recycle the cleaning fluid and filter it to remove dirt and other impurities. Circuit board immersion treatment devices are generally widely used in the electronics manufacturing industry and electronic equipment maintenance field to ensure the quality and reliability of circuit boards.

[0003] The prior art provides a circuit board immersion treatment device (Announcement No.: CN213591259U), which includes a base and a filter plate.

A vertical water pump is provided in the middle of the upper end of the liquid storage tank, and a water pipe is provided on the outside of the middle of the vertical water pump. The other end of the water pipe is provided on the outside of the water inlet. The circuit board immersion treatment device is provided with a cleaning tank, and the cleaning tank and the liquid storage tank form a water circulation structure through the return pipe. When the device is used to immerse the circuit board, the cleaning liquid in the liquid storage tank is pumped by the vertical water pump through the water pipe and the water inlet into the cleaning tank, and then enters the cleaning tank through the one-way valve and the return pipe to complete the water circulation.

When impurities enter the drain pipe, they will also enter the return pipe. Impurities entering the return pipe will affect the use of the water pump at the upper end of the liquid storage tank. Therefore, we need to propose a circuit board immersion treatment device. Utility Model Content
