An innovative process improvement software, SIGMA Link, coupled with two high performance sensors, from PI Series (3D SPI) and K Series3D (3D AOI) products families, allow driving PCBA process and interact with any Manufacturing Execution System.


One integrated solution for automated optical inspection to improve your SMT process and productivity.

SIGMA Link software suite links altogether solder paste inspection (SPI), automated optical inspection (AOI) and manufacturing execution system (MES)
SIGMA Link software suite paves the way to industry 4.0

SIGMA Link is a powerful web-based software suite currently structured around 3 modules (more to come). It’s a continuous yield improvement tool to translate SPI and AOI inspection data into useful process information. Built around a unified SPI and AOI database, a correlation of inspection data and images, SIGMA Link provides in-line monitoring, easy diagnosis of the entire PCB assembly process and full traceability of data and images. For Smart Factories, SIGMA Link is the essential element to easily interface inspection machines with Manufacturing Execution System, to enable interlocking and to pave the way to Industry 4.0.

K Series3D is a robust and proven 3D automated optical inspection system
K Series and K Series3D, the leaders’ choice in AOI

K Series and K Series3D are the reference in Automated Optical Inspection (AOI), allowing 2D and 3D inspection with very low false calls rate, for both pre-reflow and post-reflow. They are the most powerful gatekeepers to guarantee high quality level for the assembled PCB.
