- The classification process to ensure uniform particle size has a decisive impact on product quality due to the "quality of the sieve." - Major companies that monopolize the global market for functional particles have been using the "high-reliability super micro sieve" since 2008 to the present. - The attached document contains photos of the results of classifying coarse particles mixed in the sample particles using the wet classification device S-150W. A "trace amount of coarse particles that do not appear in the particle size distribution has been completely removed."

- Functional particles that are essential for high image quality in imaging devices. The first application is as spacers to maintain a uniform gap between two glass substrates. Particles with a diameter of less than 10 μm are used. - By making the gap between the glass substrates narrower and more uniform, "image quality and responsiveness are dramatically improved." - If even one large particle is mixed in, the gap between the glass substrates will widen, causing "color unevenness" in that area. Therefore, "the presence of coarse particles is not allowed, even at a rate of one in ten billion."

- Anisotropic conductive particles with a gold plating on the surface of resin, which is essential for high image quality in imaging devices. - The second application is used for connecting numerous circuits and IC chips provided on a glass substrate. - By applying double-sided tape containing anisotropic conductive particles to the circuit portion of the glass substrate, placing the IC chip on it, and pressing the terminal parts of the IC with a jig, it is possible to connect thousands of terminals in a short time. - Similar to spacer particles, "the presence of coarse particles is not allowed even at a ratio of one in ten billion."
