[Grading Technology] Wet Classification Device S-100W-D High Reliability Classification Case Study

Semtech Engineering's classification technology removes coarse particles that are not represented in the particle size distribution at the count level.

■ Increase the product quality assurance level from PPM (1/1,000,000) to PPB (1/1,000,000,000) for the contamination rate of coarse particles in product particles. ■ These particles are used in spacers for liquid crystal panels and in anisotropic conductive films (ACF) for high-density circuit connections in liquid crystal panels. ■ Samples were prepared to confirm classification accuracy. These particles exhibited good sphericity and extremely low particle size variation, so a small amount of coarse particles was added. Next, a super micro sieve (screen/filter) with a cut line of Φ5μm was used, and the images obtained during classification were analyzed with the FPIA-3000. ■ Contract Services Semtech Engineering offers contract classification services (for a fee). 1. Contract classification using wet classification equipment S-100W-D with solvent... distilled water. 2. Particle image analysis using FPIA-3000.
