What Is the Definition of Ultrasonic and Megasonic Frequency?

Sound exists at much higher frequencies, which includes both ultrasonic and megasonic ranges. While these may not be audible to human hearing, these frequencies can be used in practical applications in megasonic and ultrasonic cleaning systems.

So how do megasonic and ultrasonic cleaning systems work? When liquids and gases are subjected to high-frequency sound at powerful energy levels, it leads to the formation of microscopic tears in these mediums.

When megasonic or ultrasonic sound energy goes through these mediums, it causes the microscopic tears to form into bubbles every second, and these bubbles collapse quickly. This process is known as “cavitation.”

Cavitation bubbles are high-energy bubbles. As each of these bubbles forms and collapses quickly, it generates shockwaves. When you place an object into these cavitation bubbles, it tends to be subjected to the energy of these implosions. These cavitation bubbles are so powerful that they can dislodge dirt or other contaminants off the surface of the object exposed. This is the kind of phenomenon which both the megasonic and ultrasonic cleaning system approach utilizes.

The megasonic and ultrasonic cleaning approach is revolutionary. This cleaning approach is faster, more thorough and more efficient. Since megasonic and ultrasonic cleaning systems are contactless cleaning systems, they do not require the use of harsh cleaning chemicals or mechanical scrubbing as conventional cleaning methods do.

The ultrasonic andmegasonic cleaning system approach are also environmentally friendly, since neither use cleaning chemicals. In conventional cleaning methods, they require the application of an involved chemical disposal system to meet compliance with environmental laws.

How a Megasonic Cleaning System Removes Submicron Particles from Delicate Components

Megasonic cleaning systems use high frequency generators and transducers to clean delicate components like silicon wafers and other microelectronic devices. Megasonic cleaning has proven to be a faster, more effective, and more thorough for removing submicron particles from delicate components compared to other cleaning methods.

So how does a megasonic cleaning system work to remove such particles?

Like the ultrasonic cleaning system, the megasonic cleaning system relies on cavitation bubbles which scrub and clean away impurities from the surface of delicate components.

As a megasonic wave enters the cleaning fluid, the wave troughs produce areas of low pressure where the bubbles form. When the pressure reaches its highest peak, the bubbles collapse and releases energy which acts to scrub and clean away the contaminants on the surface of the devices being cleaned.

When the system frequency increases, the waves become closer together and there is less time for the bubbles to form. As a result, higher frequencies generate smaller bubbles. These bubbles do the gentler cleaning action on delicate components as the collapsing bubbles become less energetic.

Submicron contaminants are quite difficult to clean away because they can be small enough to be lodged in the boundary between the solid wafer and the free-flowing cleaning solution. The megasonic cleaning system enables the bubbles to move straight to the submicron particles. As the bubbles collapse, the resulting energy becomes strong enough to dislodge the submicron particles off of the surface. This cleaning process proves to be more effective in dislodging even the smallest and the most stubborn submicron particles from delicate semiconductor components and results in fewer defects in the final product. Megasonic cleaning produces a current in the solution to ensure that the small particles won't attach to the surface of the semiconductor components again.

Kaijo has been providing a wealth of expertise and experience in manufacturing ultrasonic and megasonic cleaning systems for many years. These systems can be standardized or customized according to the clients' preference. The company's "Quava megasonic cleaning system" is a cost-effective solution that can operate at either lower or higher ultrasonic frequencies for several specific cleaning applications.

How Kaijo's Ultrasonic Cleaning Generator Improves the Manufacturing Process

Ultrasonic cleaning generators create an electrical signal that activates the transducers, which in turn convert the electrical signal into ultrasonic waves in the water (or cleaning liquid) in the tank. The ultrasonic waves then produce cavitation bubbles that collapse and appear again with the frequency of the ultrasonic cleaning generator. The action of these bubbles creates a powerful scrubbing action which helps in removing surface impurities from the items that are being cleaned.

Ultrasonic cleaning is clean and environment-friendly, and also quick compared to other cleaning technologies. Small and mid-size businesses will definitely benefit from this cleaning technology as it helps in boosting productivity by cleaning products before being offered on the market, at reduced cost.

While other cleaning methods require the use of hash chemicals, Ultrasonic cleaning generators effectively clean without chemicals or with just with a benign detergent solution. Kaijo’s Phenix Legend Series generators can produce a vast range of frequencies to suit different cleaning applications.

·         Lower frequency cleaning - produces large cavitation bubbles with high cleaning energies and intensive cleaning action. Kaijo Phenix Legend models with 38 kHz and 78 kHz are ideal for this type of cleaning

·         Higher frequency cleaning - produces smaller bubbles with less energetic and intensive cleaning action, ideal for gentler and delicate cleaning tasks. Kaijo Legend Phenix models produce 100 kHz, 130 kHz or 160 kHz fall in this category.

Kaijo’s Phenix Legend Ultrasonic cleaning generator, adjusted at the right frequency, can deliver the exact type of cleaning action required for a particular application, thus making cleaning more efficient.

Cleaning parts with irregular surfaces is sometimes challenging. Chemicals often diffuse slowly in holes or crevices and mechanical cleaning cannot reach deep crevices. Using Kaijo's Water Resonance System with an ultrasonic cleaning generator will remarkably improve the cleaning action by conditioning the water. This produces a more even distribution of the bubbles for effective cleaning power which can be five times better than that of the cleaning systems without water resonance.

How an Ultrasonic Cleaning System Works and the Benefits It Provides to Manufacturers

An ultrasonic cleaning system can significantly improve the productivity of many businesses and manufacturers. Such systems remove impurities and surface matter from components and clean products during the manufacturing process.

How does an ultrasonic cleaning system work? A turnkey ultrasonic cleaning system uses a generator and one or more transducers along with a tank. An ultrasonic generator produces an electric signal (at different frequencies) and activates the transducers. The transducers then transform the electric signal into ultrasonic waves in the water in the tank. The water may have cleaning solutions to improve the ultrasonic cleaning process.

When the transducers generate compression waves in the water cavitation bubbles form in the liquid. These bubbles collapse and form again between the compression peaks. The formation and collapsing of bubbles create a robust scrubbing action when in contact with the item to be cleaned.

Kajio's Phenix III Ultrasonic Cleaning System runs at 26 kHz or 38 kHz and delivers up to 1200 Watts of cleaning power. It can clean on either lower or higher frequencies depending on the type of cleaning action required.

The system comes as the Phenix III ultrasonic generator with a stainless steel cleaning tank that already has transducers installed. It is cost-effective and available in four models with outputs at two frequencies and with 600W or 1200W power options. The cleaning tank also comes in different sizes, the biggest being 4.5 cubic feet. The ultrasonic cleaning systems are developed for low noise as well as no erosion for the parts and components to be cleaned.

Kajio's ultrasonic cleaning systems offer a cost-effective, quick and efficient solution for small and mid-size businesses and manufacturing plants. You can learn by reading the blog article titled “How an Ultrasonic Cleaning System Works and the Benefits It Provides to Manufacturers”.
