Automated Optical Inspection (AOI) is a powerful tool for assessing workmanship compliance in Prototype as well as Production PCB assembly environments. With advanced lighting, optics, and image processing capabilities, the machines greatly enhance inspection repeatability, accuracy and throughput. AOI plays a vital role in test strategies designed to ensure the highest possible quality throughout each phase of a product’s life cycle.

Automatic Optical Inspection (AOI) addresses ever-increasing density, diversity, and quality requirements of PCBs by maximizing resources to increase production efficiency in a competitive business that leaves little margin for error. AOI eliminates the subjectivity and variability necessarily associated with manual visual inspection. Systems are integrated into the automatic assembly processes to provide 100% visible component and solder-joint inspection.

Benchmark develops applications and deploys solutions based on OMRON and Teradyne AOI platforms. The OMRON VT-WIN represents a true inspection innovation by incorporating unique zoom, off-axis and patented color-illumination techniques. The Teradyne design uniquely allows for large-standoff PTH pre- and post-Wave solder-side inspections.  A dedicated engineering staff provides quick-turn programming, support, and continuous improvement. Low cost and quick-turn programming efforts make AOI a practical and powerful quality tool for prototypes and high-volume assembles alike. AOI reflects Benchmark Electronics’ commitment to provide state-of-the-art and cost-effective test and inspection solutions for today’s high-technology products.
