Built on Saki’s proven high-rigidity gantry structure, the 3Si/3Di-EX Series introduces a modular hardware design that allows seamless optical unit upgrades, ensuring long-term adaptability to evolving inspection needs. With a shared gantry and a unified software interface, the next-generation system offers sustainability, efficiency, and superior usability for high-precision inspection.
Optimized software and AI-driven inspection
Key features of the series include:
- One Programming, unified SPI and AOI inspection program data that eliminates redundant setup and programming tasks;
- Easy Programming, simplified and automated program creation that minimizes operator workload and enhances productivity;
- AI Assist*, which reduces false positives through hybrid AI-powered re-evaluation, improving efficiency and further counters operator workload; and
- AI OCR*, AI-powered optical character recognition that ensures stable character inspection despite variations in print quality and position, boosting productivity and eliminates the need for specialized skills.
Smart factory automation for enhanced efficiency
The 3Si/3Di-EX Series is engineered to maximize productivity, efficiency and quality control with advanced machine-to-machine (M2M) connectivity and full Smart Factory integration. The key here is Saki Link, which seamlessly connects SPI and AOI systems, enabling real-time data sharing and optimized inspection flow. Furthermore, it provides centralized control across multiple inspection systems within a production line, eliminates bottlenecks and improves quality control.
These advanced automation capabilities allow manufacturers to streamline processes and achieve greater levels of operational efficiency.
Saki continues to push the boundaries of inspection technology, delivering precision, automation, and sustainability to meet the demands of modern electronics manufacturing. With ‘Made in Japan’ quality and a commitment to customer-driven innovation, the 3Si/3Di-EX Series ensures manufacturers stay ahead in the pursuit of manufacturing excellence.
