Selling Points


Size: Approximately 200m²

    • Thanks to the spacious area, we can consider setting up curtains or clean booths within the cleanroom to create an area with even higher cleanliness levels. 
    •  If a cleanroom is not required, there are other inspection rooms available.

Performance of Class 1000

    • Measured with a particle counter when inspecting automotive semiconductor parts, this reflects actual achievement.
    • The room maintains a constant positive pressure environment to prevent contamination from being released to the outside.

Unique Methods to Maintain Cleanliness

      • We have established four principles for the cleanroom and are committed to them daily.
      • We wear cleanroom suits.
      • We have established rules for which items can and cannot be brought into the cleanroom.
      • We are also creative about our indoor cleaning methods.
    • Cleanroom Four Principles

Years of Inspection Experience

    • Since the company’s foundation 49 years ago, we have continuously conducted inspections.
    • We have acquired significant know-how from these years of sustainability.

Genre-less Inspection Experience

    • We recently started ceramics, thus urgently needed to develop skilled individuals for ceramic inspection. 
    • This variety of inspection experience across various industries leads to smooth launches of new projects.

Maintaining Inspection Accuracy

    • We have developed a unique inspector certification system and training curriculum.
    • We have also established a unique maintenance check system.

Handling of Micro Products

      • We select suitable tools (such as tweezers) for each product.
      • Through a custom practice curriculum, handler specialists are created.

Innovative Ideas for Rapid Development, Consistent Inspection, and Efficiency

    • Example 1: Use of Tablets

    • We deal with a large number of physical photos, such as defective samples and feedback information with inspections. Therefore, we initiated management via tablet, which contributes to inspection accuracy and cost reduction.

    • Example 2: Initial Layout for New Projects

    • or new inspection projects, understanding inspection standards and common understanding of defects are crucial. For early stage, consistent inspection-capable personnel, we design a layout that allows for easy idea exchange. Later, when inspectors become independent, conversation is minimized and prevention of mixing different items becomes critical, hence we modify the layout.
