Using Ultrasonic Cleaning Systems to Safely and Effectively Clean Circuit Boards

Ultrasonic cleaning systems work by using a transducer plate in contact with water or a mild cleaning solution to produce cavitation bubbles that scrub the items to be cleaned.

Such systems remove impurities more effectively, thoroughly, and safely than conventional cleaning methods. They don't use traditional scrubbing or harsh cleaning chemicals. These attributes make ultrasonic cleaning systems especially ideal for cleaning circuit boards.

Kajio offers a wide range of ultrasonic cleaning system equipment. Apart from offering standard equipment, Kajio can also help customers select the system that best matches specific circuit board cleaning specifications and requirements.

Among the advantages of using ultrasonic cleaning systems are:

·         Rapid and thorough cleaning of all surfaces

·         Cavitation bubbles can clean and scrub complex geometries, through holes and into crevices

·         The frequency can also be adjusted to meet specific cleaning intensity

·         Water-based cleaning solutions which don’t require the use of harsh chemicals

The benefits of using ultrasonic cleaning systems include:

·         It is cost-effective

·         It eliminates the need to purchase, store and use harsh cleaning chemicals

·         It helps increase productivity and improve output quality

·         It can be used both for gentle cleaning of delicate parts and robust cleaning to remove heavier impurities

·         Its complete cleaning action can remarkably reduce failure rates

·         It is environment-friendly

When purchasing an ultrasonic cleaning system, consideration of the operating frequencies and the system's physical configuration are critical for obtaining the best cleaning performance possible. In addition to selecting the appropriate frequencies, adequate system power is important for industrial cleaning applications. Kaijo can evaluate a circuit board cleaning process and can recommend the appropriate ultrasonic cleaning system configuration.

Selecting Ultrasonic Transducers for Industrial Cleaning Applications

Ultrasonic cleaning systems consist of three parts: the ultrasonic generator, the transducer, and the cleaning tank. The generator produces an electric signal and the ultrasonic cleaning transducer converts the signal into compression waves into the cleaning solution. The waves then produce cavitation bubbles that do the scrubbing action of the components to be cleaned.

The role of the transducer is quite crucial for the cleaning of components, parts, and tools. It produces compression waves through the piezoelectric material that expands and contracts when subjected to the electric signal. The transducer changes the height of the piezoelectric material with the help of the electric signal that comes from the ultrasonic generator. That way, the transducer produces compression waves when its metal surface, tightly bonded to the surface, vibrates at a selected frequency.

Ultrasonic cleaning transducers need to be heavy, rugged and durable enough to withstand severe vibrations and immersion in cleaning solutions, as well as to generate powerful compression waves. Their surfaces must also be designed to resist pitting due to the action of cavitation bubbles.

Kaijo offers transducers that are heavy, rugged and durable. They are hermetically sealed in 316L polished stainless steel housing and are designed to withstand immersion in cleaning temperatures up to 100 degrees Centigrade.

Ultrasonic cleaning transducers are available in bolt-on, immersible or mounted versions. Immersible versions are independent units connected to the generator via a cable can be moved and placed anywhere in the cleaning tank. Mounted tranducers are integrated into cleaning tanks and are usually purchased for specially designed cleaning applications. Bolt-on transducers are similar to mounted, but are bolted onto the sides or bottom of cleaning tanks in single or multiple-unit configurations.

Kaijo’s ultrasonic cleaning systems range in frequencies from 26 kHz to 2MHz. Their variable power output has maximums of 600W or 1200W. Kaijo is able to evaluate a customer’s needs and propose the right custom solution.
