Application Cases

With the advancement of technology, cleaning techniques have been applied to numerous fields such as industrial automation, automotive manufacturing, machinery manufacturing, aerospace, shipbuilding, and electronics manufacturing. The continuous development and expansion of application fields necessitate progress and evolution in cleaning technologies. Traditional cleaning methods are contact-based, which cannot effectively clean delicate electronic instruments and tiny cracks. Moreover, contact can cause damage to precision industrial electronic devices, affecting their accuracy. Faced with these numerous challenges, there is an urgent need for an entirely new cleaning technology that can meet the daily cleaning requirements of industrial processing and precision instrument manufacturing.

Ultrasonic cleaning technology, with its advantages of high quality, high speed, pollution-free, ease of automation, and no limitation on surface morphology, has been rapidly developed and widely applied in both daily life cleaning and industrial cleaning.

Aigtek's ATA-3000 series power amplifiers are widely used in the field of ultrasonic cleaning. With a maximum output voltage of 160Vpp and a -3dB bandwidth of DC to 120kHz, they can drive most ultrasonic cleaning transducers.

Experiment Title: Ultrasonic Erosion Experiment on Aluminum Foil

Experiment Principle:Ultrasonic cleaning involves the use of ultrasonic transducers to generate ultrasonic waves. Under the influence of these waves, tiny bubbles in the liquid rapidly expand and collapse, creating powerful shock waves and microjets. These shock waves and microjets can disrupt the adhesion of dirt and metals on the surface of the object being cleaned, causing the contaminants to detach and disperse into the liquid. Additionally, the vibration of the bubbles can scrub solid surfaces and penetrate into cracks to perform cleaning.

Experiment Process:A signal generator outputs a sine wave signal with a frequency of 40kHz and an amplitude of 3Vpp, which is input into an ATA-3080C high voltage amplifier. After amplification by the power amplifier, a voltage signal of 160Vpp is output to drive the ultrasonic transducer, generating ultrasonic waves. The bubbles produced by the ultrasonic vibration are used for the erosion of aluminum foil.

Experimental 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 ablation. By adjusting the driving voltage of the transducer, the ablation rate can be changed, making it suitable for cleaning metal contaminants on the surface of electronic devices.

Function of the Power Amplifier:The power amplifier is the core component of the entire experiment. In this experiment, it provides a stable, low-distortion AC signal with an amplitude of 100-160Vpp to drive the ultrasonic transducer.
