Ultrasonic cleaning of PCB boards for blockchain mining involves immersing the boards in a cleaning solution and using high-frequency sound waves to create microscopic bubbles that gently remove dust, corrosion, solder flux, and other contaminants from the surface and intricate components of the PCB. This thorough cleaning process restores the board’s optimal performance by improving electrical conductivity and preventing issues caused by debris or residue. Ultrasonic cleaning is particularly effective for complex or sensitive components, as it reaches areas that are difficult to clean manually, ensuring that the mining equipment runs efficiently and reliably.
