Technical Field

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

[0002] Contaminants refer to any surface deposits, impurities, inclusions, and adsorbed substances that reduce the chemical, physical, or electrical properties of printed circuit boards to unqualified levels. Cleaning is the process of removing contaminants, mainly using solution cleaning methods. Through the dissolution or chemical reaction between the contaminants and the solvent, the physical or chemical bonds between the contaminants and the printed circuit board are destroyed, thereby achieving the purpose of separating the contaminants.

[0003] In the process of cleaning printed circuit boards, a key step is to ensure that the circuit board is firmly clamped to prevent it from moving or vibrating. Afterwards, professional spraying equipment is used to evenly spray the cleaning liquid on the surface of the printed circuit board to remove dirt and impurities on it. However, a common problem is that the cleaning liquid often cannot be quickly air-dried after being sprayed onto the surface of the printed circuit board. This may not only cause wet cleaning liquid to remain on the surface of the circuit board, thereby affecting the performance of the printed circuit board, but may also accelerate the oxidation and corrosion of the circuit board, thereby reducing the practicality and efficiency of the entire printed circuit board cleaning device. Therefore, how to quickly and effectively make the cleaning liquid dry on the surface of the circuit board has become an important research direction for improving the performance of the printed circuit board cleaning device.
