Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a circuit board cleaning machine. Background Art

[0002] The names of circuit boards include: ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, circuit boards, PCB boards, aluminum substrates, high-frequency boards, thick copper boards, impedance boards, PCBs, ultra-thin circuit boards, ultra-thin circuit boards, printed circuit boards, etc. Circuit boards miniaturize and visualize circuits, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layouts. After a long period of placement, the surface of the circuit board will absorb a large amount of dust, which can easily cause poor contact of the circuit board, and thus it needs to be cleaned.

[0003] The patent with the national patent publication number: CN212681890U discloses a circuit board cleaning machine. The application states: "After cleaning the dust on the circuit board, the dust on the circuit board will directly settle to the bottom of the cleaning box, and when the circuit boards are taken out of the cleaning tank one by one, the dust at the bottom of the cleaning box is likely to float up and float onto the circuit board." Although the application solves this problem, it has the following defects:

[0004] The circuit board cleaning machine in this application fails to treat the water after cleaning the circuit board. The dust dropped by the circuit board cleaning will mix into the water. Although the circuit board will not cause dust floating when it is taken out, it still affects the cleaning effect of the circuit board, and requires frequent water changes, resulting in a waste of water resources. For this reason, we propose a circuit board cleaning machine. Utility Model Content
