Frequency range of ultrasonic wave

Commonly used ultrasonic frequency and its application scope:
1, generally speaking, the frequency greater than 20KHZ can be regarded as the category of ultrasound.
2. Ultrasound frequencies used for cleaning are generally between 25KHZ and 130KHZ. The common operating frequencies are 28KHZ, 33KHZ, 40KHZ, 80KHZ, 100KHZ, 120KHZ, etc.
3. In theory, the higher the frequency, the higher the cleaning density, the higher the cleaning cleanliness, but the smaller the relative strength, more used for precision cleaning. The lower the frequency is the opposite. Therefore, the frequency below 40KHZ is generally used for cleaning common industrial parts or more dirt, such as hardware and machinery parts degreasing and dewaxing. The frequency above 40KHZ is mostly used for precise cleaning of precision parts, such as optical/optoelectronic glass devices and semiconductor materials/devices.
Application scope and equipment application of ultrasonic cleaning:
1. Ultrasonic cleaning is widely used. With the development of industrial technology, the cleanliness requirements of various industrial parts are relatively higher and higher. Especially in the optoelectronics and semiconductor industry, the cleanliness requirement has reached um level.
2. The company has made great progress in the manufacture and application of high-frequency ultrasonic technology through years of research and development. The frequency of our high frequency cleaning machine is 40KHZ, 80KHZ, 100KHZ, 120KHZ, 130KHZ and so on. It is mainly used for cleaning precision industrial parts, such as liquid crystal display (STN, TFT, PDP, etc.); semiconductor silicon; hard disk; electrical vacuum devices.
3. With its simple and unique shape, wide range of application, reliable and high performance, long service life, simple and convenient installation method, the rod-type ultrasonic device developed by Wiggott is among the advanced ultrasonic technology in the world.
