Megasonic Cleaners

How Megasonic Cleaning Works

Megasonic cleaning technology relies on the same basic principle as ultrasonic cleaning using sound waves transmitted through a liquid medium at much higher frequencies. At megasonic levels, the cavitation bubbles are smaller and less violent, producing a gentle yet highly effective scrubbing action. This allows removal of particles as small as 0.1 µm while protecting delicate coatings, wafers, and substrates.

The process ensures:

• Uniform cleaning coverage

• Reduced particle redeposition

• Shorter cycle times

• Minimal mechanical stress on components

Types of Megasonic Cleaners

Shower-Type Megasonic Cleaner

The shower-type megasonic cleaner delivers high-frequency energy through a continuous flow of cleaning liquid from a precision shower head. The liquid stream disperses evenly across the surface, providing consistent cleaning performance and avoiding turbulence or shadowing.

Key advantages:

• Uniform energy distribution across large or flat surfaces

• Continuous liquid flow prevents particle re-attachment

• Ideal for wafers, optics, and precision glass components

Typical applications:

• Semiconductor wafer processing

• Photomask and flat-panel display cleaning

• Optical lens manufacturing and coating preparation

Batch-Type Megasonic Cleaner

The batch-type megasonic cleaner is designed to process multiple components simultaneously within a single tank. This configuration combines high throughput with precise cleaning uniformity, making it suitable for production lines and laboratories.

Features:

• Adjustable power and frequency settings

• Programmable cleaning cycles and temperature control

• Stainless-steel construction with chemical-resistant lining

Applications:

• Electronic assemblies and precision machined parts

• Medical devices and instruments

• R&D and pilot production environments

Batch-type systems are valued for their versatility and efficiency, allowing manufacturers to clean multiple parts quickly while maintaining consistent quality standards.

Cover-Type Megasonic Cleaner

The cover-type megasonic cleaner features an enclosed or semi-enclosed tank with an integrated lid or cover system. This design minimises liquid loss, reduces airborne contamination, and helps maintain consistent temperature and acoustic energy during cleaning.

Advantages:

• Controlled environment reduces contamination risk

• Improved thermal stability for critical processes

• Lower noise levels and safer operation

Typical applications:

• Medical and laboratory environments

• Semiconductor and optical component cleaning

• Processes requiring cleanroom compatibility

Benefits of Using Megasonic Cleaners

Gentle Yet Powerful Cleaning

Megasonic technology eliminates contaminants without scratching or altering surfaces, making it ideal for delicate substrates and coated materials.

Energy and Chemical Efficiency

The process reduces chemical consumption and shortens cleaning cycles, resulting in lower operating costs and improved environmental performance.
