Investigation of microparticle visualization to uncover the true culprit of foreign substances.
The causes of defects are 'visible.' Identify the source and flow of foreign substances and lead to improvements on the spot.
"Unexplained foreign substances do not disappear" and "Even with countermeasures, they recur" — we solve such on-site issues all at once with our fine particle visualization system. This service uses laser light and a high-sensitivity camera to "visualize" invisible fine particles and airflow movements in real-time, providing a field investigation solution to identify the root cause of defects. We visualize "where it occurs, how it moves, and where it adheres" on-site, which could not be grasped with conventional measurements. Factors that are intricately intertwined, such as work actions, equipment structure, and transport processes, can be intuitively understood through video. This enables a reliable investigation of causes that does not rely on intuition or guesswork. Furthermore, based on our extensive field experience, we also provide specific improvement proposals based on the visualization results. We support comparative evaluations before and after improvements, which is a significant feature as it allows the "effects of countermeasures to be visible." Our system has been widely adopted in fields such as semiconductors, films, pharmaceuticals, and food, where strict quality control is required, contributing to the reduction of defects and prevention of recurrence in a short period. ■ Numerous example videos are available on our company website.
