PERSCI Offline Automated Optical Inspection (AOI) System

The PERSCI Offline AOI System is a high-precision automated optical inspection solution designed for standalone PCB inspection. It allows manufacturers to inspect printed circuit boards separately from the production line, ensuring quality control at any stage of assembly. Utilizing AI-powered image processing and high-resolution cameras, the system accurately detects soldering defects, missing components, misalignments, and surface anomalies. This flexible offline system is ideal for low-to-medium volume production, prototyping, and quality assurance labs.
