Cleaning Applications


Since 1973, Ralsonics has been supplying ultrasonic cleaning equipment of all sizes, spanning 15 industries. Our equipment is known for its reliability. We fully understand the requirements and processes of our customers before specifying any equipment for use. Owing to over four decades of experience in ultrasonic cleaning, we have learned and developed best practices for cleaning components in each industry.

Semiconductor Industry

The semiconductor industry is a critical sector that forms the backbone of modern technology. It encompasses the design, fabrication, and distribution of semiconductor devices, which are essential components in electronic circuits. Semiconductors are materials that possess unique electrical properties, allowing them to control the flow of electricity. This capability enables semiconductors to perform various functions such as amplification, switching, and storage of electrical signals.

The semiconductor industry drives innovation and powers advancements in a wide range of sectors, including information technology, telecommunications, automotive, healthcare, and consumer electronics. Semiconductors are used in microprocessors, memory chips, sensors, transistors, and integrated circuits that form the core of electronic devices. The industry is characterized by intense research and development activities to improve performance, reduce size, increase efficiency, and lower costs.

Ultrasonic cleaning is considered the ideal cleaning method for semiconductors due to several key reasons. Semiconductors are highly sensitive electronic components that require gentle yet effective cleaning to ensure their optimal performance. Ultrasonic cleaning achieves this balance by using high-frequency sound waves to generate microscopic bubbles in a cleaning solution. These bubbles implode near the semiconductor’s surface, creating a scrubbing action that dislodges contaminants without causing damage.
