Particle Removal System MICROCLEANER^🄬 FPS

What is 'particles'?

Particles are a generic term for nano- to micro- sized fine particles, which, if generated or mixed in during the manufacturing process of electronic devices and components, may adversely affect product quality and yield. Particles are a variety of organic and inorganic materials, including cutting dust from processing and molding, dust in the air, and metal and resin shavings from contact and wear of moving parts of manufacturing equipment.

Among these, one of the biggest sources of particles is the workers themselves. The sebum and skin flakes on the human body, as well as fiber fragments, and even the ingredients contained in cosmetics and hair products, are all particles that can contaminate product surfaces and damage the electrical reliability of products. Of course, the workers on site wear dust-free clothing and masks depending on the cleanliness of the site, but it is difficult to eliminate all particles emitted by people.

What happens if you don't remove the particles?

For example, many camera modules and optical sensors are used in modern cars. If particles remain in the components during the manufacturing process of these sensors, they can contaminate important components such as image sensors and optical elements, causing serious accidents due to malfunction or false detection.

In addition, camera modules for mobile devices are becoming smaller and more sophisticated, and even small particles in small quantities can affect product quality. The particle removal process is increasingly demanding higher levels of cleaning quality.

What kind of cleaning agent should be used to remove particles?

Fluorine-based cleaning agents such as HFE (hydrofluoroether) and HFC (hydrofluorocarbon), surfactants, and aqueous cleaning agents containing alkaline components, as well as pure water, have been used as particle removal cleaning agents. The advantages and disadvantages of each are summarized below.
Conventional cleaning systems did not satisfy all of the requirements for cleaning performance, cost, safety, and environmental compatibility.

Particle Removal System MICRO CLEANER FPS System

		Based on the know-how we have cultivated in the field of flux cleaning, KAIKEN TECH has newly developed the MICRO CLEANER FPS, a system dedicated to particle removal. This cleaning system, which achieves both high particle removal performance and reduced environmental impact, can also remove small-diameter particles and small quantities of particles, which have become an issue as electronic devices become more sophisticated.

Zero wastewater, one-liquid cleaning system

As the cleaning agent does not contain any non-volatile components, it is possible to clean and rinse with a single liquid, just like fluorine-based cleaning agents. As no water is used in the rinsing process, there is zero wastewater! In addition, by using a combination of Distiller and a filter mechanism, the residual and re-adhesion of dirt components such as particles that have become mixed in or dissolved in the liquid are thoroughly suppressed, so it is possible to operate the system with almost no need for liquid replacement, just by replenishing the new liquid.
