The Best Cleaning Solution for the ESG Era: Ultrasonic + Microbubble

• The non-contact nature of ultrasonic technology is particularly suited for components with complex structure
• Our microbubble technology has been tested by leading semiconductor manufacturers for cleaning wafer cassettes and PFA tubing, with outstanding results
• As ESG awareness rises globally, ultrasonic combined with microbubble cleaning can reduce the use of chemical solutions and minimize water waste

Fully customizable across the entire process flow to match customer product geometry and process requirements !
Large contaminants are first removed using multi-frequency ultrasonic waves, followed by more refined cleaning with microbubbles smaller than a pore, effectively reducing the risk of residual impurities.

A DI water rinse tank then provides a final cleaning pass, meeting the most rigorous cleanliness standards. The process concludes with a drying module that can be configured with heated nitrogen, infrared irradiation, or other particle-free drying methods depending on product characteristics, ensuring no watermarks or contamination after processing and achieving optimal cleaning quality.

Japan is widely recognized as the global leader in mic robubble cleaning technology. With over 40 years of experience collaborating with Japanese companies, Lim Chemical Co., Ltd. has worked with industry partners to develop microbubble cleaning technology tailored for high-specification applications such as semiconductor manufacturing!

Our solution is capable of generating high-density microbubble water that exceeds industry standards. Combined with our proprietary technology and customized to specific requirements, it achieves both superior cleaning performance and a compact, refined design.

 

• The reference design is currently estimated to be compact enough to fit within a 20-inch travel suitcase.

• The typical microbubble output concentration in the industry is around 1,000–2,000 pcs/ml, but Lim Chemical's equipment produces microbubbles at twice that concentration !

   

Through its proprietary technology, Lim Chemical is capable of producing nanoscale bubbles even smaller than microbubbles. In addition to handling finer particles, these bubbles also offer the dual benefits of oil removal and sterilization.

Based on molecular dynamics, an ordered electrostatic polar arrangement (+/−) forms at the gas–liquid interface within bubbles only a few nanometers in diameter.
This electrostatic effect promotes lipid breakdown and sterilization

According to the formula $\Delta p = 2\sigma / d$, at a diameter of d = 100 nm, the internal pressure differential of a bubble in water can reach approximately 30 atm (standard atmosphere). If surface tension is present in the water, the internal pressure of the bubble will also increase accordingly.

• When bubbles collapse, they generate pressure waves capable of physical stripping.
• The high surface-area-to-volume ratio of the bubbles allows them to adhere readily to surfaces, enabling effective removal of attached contaminants and enhancing overall cleaning performance.

This is a device that makes the power consumption of every piece of electrical equipment completely transparent.
With global warming on the rise, the ESG movement has taken the world by storm. International organizations and governments everywhere are rolling out new regulations, making energy saving and carbon reduction more urgent than ever.

This product allows you to simultaneously achieve three critical goals: reducing electricity costs, formulating energy-saving measures, and reducing carbon dioxide emissions.
