The COVID-19 pandemic brought about a significant surge in demand for electronic products, driven by the rapid transition to remote work and learning. This shift emphasized the essential role played by 3D automated optical inspection (AOI) technology in ensuring the quality of electronic devices like smartphones, laptops, and consumer electronics. Simultaneously, the pandemic accelerated the adoption of advanced technologies, such as 5G, which rely on intricate electronic components.

Consequently, the heightened demand for electronic products during the pandemic led to an equally substantial increase in the demand for 3D AOI equipment. Manufacturers recognized the imperative of meeting stringent quality standards to satisfy consumer and business expectations, bolstering the growth of the 3D AOI market during this period. This surge in demand underscored the critical role played by 3D AOI technology in ensuring the reliability and functionality of electronic products in a rapidly changing landscape.

LATEST TRENDS

Integration of Structured Light and Laser Scanning to Enhance Resolution of 3D AOI Systems

Recent developments in sensor technologies, specifically structured light and laser scanning, have significantly improved the resolution and accuracy of 3D automated optical inspection (AOI) systems. Structured light sensors project a pattern of light onto the object being inspected and capture images of the deformed pattern. By analyzing this deformation, they reconstruct the object's 3D shape. These sensors are known for their affordability and versatility, making them suitable for inspecting objects of various sizes and shapes. In contrast, laser scanning sensors utilize laser beams to scan the object and measure distances at each point, allowing for precise 3D shape reconstruction by stitching together distance measurements. While laser scanning sensors tend to be more expensive, they offer superior resolution and accuracy.

Both structured light and laser scanning sensors have enhanced 3D AOI systems by increasing image resolution, improving measurement accuracy, and enabling the inspection of objects with complex shapes. Examples of their application include the CyberOptics SQ3000 3D AOI system, which combines structured light and laser scanning for high resolution and accuracy and is capable of detecting defects as small as 10 micrometers. Similarly, the MVP Vision Systems GEM III 3D AOI system employs laser scanning sensors for high-resolution inspections, capable of detecting defects as small as 5 micrometers. Lastly, the Omron VT-iG3D 3D AOI system utilizes a structured light sensor for high-resolution inspections, detecting defects as small as 10 micrometers.

• According to the U.S. National Institute of Standards and Technology (NIST), AI-based optical inspection systems have improved defect detection accuracy by 38% compared to traditional 2D systems. The adoption of 3D AOI machines with integrated deep learning algorithms has allowed electronic manufacturers to reduce false call rates to below 0.5%, enhancing production efficiency and quality assurance.

• According to the International Federation of Robotics (IFR), more than 553,000 industrial robots were installed globally in 2023, a 7% rise compared to the previous year. The increasing robotic deployment, especially in surface-mount technology (SMT) lines, has accelerated the demand for 3D AOI systems that provide precise solder joint inspection and component alignment validation.
