The Application of Power Amplifiers in Ultrasonic Erosion Experiments on Aluminum Foil
With the advancement of technology, cleaning techniques have been applied to numerous fields such as industrial automation, automotive manufacturing, mechanical engineering, aerospace, shipbuilding, and electronics manufacturing. As application areas continue to develop and expand, cleaning technologies also need to progress and evolve. Traditional cleaning methods are contact-based, which are not suitable for cleaning delicate electronic instruments and tiny crevices. Moreover, contact can cause damage to precision industrial electronic devices, affecting their accuracy. Faced with these challenges, there is an urgent need for a new type of cleaning technology that can meet the daily cleaning requirements of industrial processing and precision instrument manufacturing.
Ultrasonic cleaning technology has been prioritized and rapidly developed due to its high quality, high speed, non-polluting nature, ease of automation, and the ability to clean regardless of surface morphology. It has been widely applied in both daily life cleaning and industrial cleaning. The ATA-3000 series of amplifiers from Antai Electronics has been widely used in the field of ultrasonic cleaning. With a maximum output voltage of 160Vpp and a -3dB bandwidth of DC to 120kHz, it can drive most ultrasonic cleaning transducers.
Experiment Name: Ultrasonic Erosion Experiment on Aluminum Foil
Experiment Principle: Ultrasonic cleaning works by using ultrasonic transducers to generate ultrasonic waves. Under the influence of these waves, tiny bubbles in the liquid rapidly expand and collapse, creating strong shock waves and microjets. These shock waves and microjets can disrupt the adhesion of contaminants and metals on the surface of the object being cleaned, causing them to detach and disperse into the liquid. Additionally, the vibration of the bubbles can scrub solid surfaces and penetrate into crevices to vibrate, achieving the cleaning effect.

Experiment Process: A signal generator outputs a sine signal with a frequency of 40kHz and an amplitude of 3Vpp. This signal is input into an ATA-3080C high-voltage amplifier. After amplification, the amplifier outputs a voltage signal of 160Vpp to drive the ultrasonic transducer, generating ultrasonic waves. The bubbles produced by the ultrasonic vibration are used to erode the aluminum foil.
Experiment Results: When ultrasonic radiation is applied to the cleaning agent, tiny bubbles begin to vibrate under the influence of the sound waves. It is evident that the aluminum foil shows signs of erosion. By adjusting the driving voltage of the transducer, the rate of erosion can be changed, making it suitable for cleaning metal contaminants on the surface of electronic devices.
