200KHZ 30W High Frequency Ultrasonic Transducer For High Precision Ultrasonic PCB Generator

The ultrasonic vibrator produced by our company is a piezoelectric ceramic conversion device, which converts high-frequency sinusoidal voltage signals into high-frequency mechanical vibration signals, which are installed on the bottom or side walls of the cleaning tank, and are transmitted through the tank and act on the cleaning medium. The vibration signal of the vibrator is converted into a cavitation effect, and the attachment of the object is quickly peeled off to achieve the purpose of cleaning.
The ultrasonic vibrators produced by the company have the following characteristics: low heat generation, good thermal stability, low resonance impedance, good consistency between frequency and static capacitance, and complete and smooth waveforms of frequency and impedance.
Ultrasonic vibrators have multiple resonance points. Using the second and third resonance points of the vibrator, we have developed dual-frequency ultrasonic vibrators and three-frequency ultrasonic vibrators, which are effective in ultrasonic cleaning machines. The company can customize them according to your needs. Various types of ultrasonic vibrators can achieve a higher level of cleaning effect.

The mechanism of ultrasonic cleaning is to make use of the physical effects such as cavitation, radiation pressure and sound flow in the cleaning liquid. It can exfoliate the machinery produced by the dirt on the cleaning parts, and can also promote the chemical reaction between the cleaning liquid and the dirt, so as to achieve the purpose of cleaning the object. The frequency of the ultrasonic cleaning machine can be selected by 10~500 kHz according to the size and purpose of the cleaning material, generally more than 20~50 kHz. With the increase of the frequency of ultrasonic transducer, Langerhans oscillator, longitudinal oscillator and thickness oscillator can be used. In the miniaturization aspect, radial vibration and flexural vibration are also adopted. Ultrasonic cleaning has become more and more widely used in various industries, agriculture, household equipment, electronics, automobile, rubber, printing, aircraft, food, hospital and medical research.

High-frequency ultrasonic cleaning is suitable for the fine cleaning of computers and microelectronic components; megahertz ultrasonic cleaning is suitable for the cleaning of integrated circuit chips, silicon wafers and wave films. It can remove micron and sub-micron dirt without any damage to the cleaning parts. Therefore, considering the cleaning effect and economy, the frequency is generally selected in the range of 20-130KHZ. Of course, the correct selection of the frequency is very important, and the selection of the specific suitable working frequency requires certain experiments to obtain
