The Ultimate Guide To Automated Optical Inspection 

Automated optical inspection (AOI) is a type of visual inspection for printed circuit boards that utilizes a camera. It can detect quality and catastrophic failure defects. It is a common technique used in manufacturing processes. AOI is also a non-contact test method. It has a number of advantages, including its low cost and ease of use. In addition, it is more efficient and less time-consuming than other methods.

3D automated optical inspection

The global 3D automated optical inspection equipment market is characterized by the growing adoption of smart devices and the growing electronic content in automobiles. Moreover, increasing investments from governments of developing countries are driving the market. In addition, the market is expected to witness significant growth over the forecast period. The report also features an analysis of key players operating in this market.

The PCB industry was the largest application segment in 2015, and it is expected to grow at a CAGR of XX% from 2016 to 2030. This growth can be attributed to the increasing demand for miniaturized electronic components. Manufacturers of electronic components have increased their focus on miniaturization in order to meet this demand. One such company is Koh Young America, which has developed an innovative 3D automated optical inspection system. The company’s Zenith Series uses True 3D technology to measure real-time, 3D component shapes. Moreover, the system can accurately detect solder joints, foreign materials, and patterns. The system also features AI-powered capabilities that overcome human errors and deliver reliable defect classification.

2D automated optical inspection

In this report, the global SMT 2D Automated Optical Inspection (AOI) market is analyzed. The study focuses on the key factors influencing the market growth. It also provides detailed information on the key players in the market, including their recent product launches, upcoming strategies, and business development plans. The report also presents the competitive landscape and the year-on-year growth rate of the global market.

The market for 2D 3D automated optical inspection equipment is expected to grow at a CAGR of 6.5% during the forecast period, due to factors such as increasing demand for miniaturized electronics, increasing number of applications for AOI equipment, and increasing adoption of advanced inspection technologies. The 2D AOI equipment will account for a larger market share during the forecast period, owing to its cost effectiveness, simplicity, and ease of installation.

2D AOI machines are available in different configurations. For example, the QX250i system from CyberOptics can inspect PCBs with dimensions of up to 400 x 308mm. The system’s eighty-megapixel sensor on each SIM module enables high resolution inspection at a speed of 110 cm/sec. The system also has an integrated sensor interpolation module (SIM), which allows for on-the-fly measurement and calibration-free data processing. This system is ideal for final inspection, as well as for through-hole inspection after wave soldering. It can also perform manual inspections.


A 2D automated optical inspection system is a low-cost, automated optical inspection system. These systems use multiple side-angle cameras to detect defects such as part markings on through-hole components and solder quality on J-Lead devices. As compared to a 3D system, a 2D inspection system can give better inspection results. However, a 2D system cannot measure true volumetric height, so it is limited in its performance. Furthermore, it cannot detect printed part nomenclature, polarity marks, or color. Furthermore, there are still some drawbacks: 2D systems require additional programming and cycle time. In addition, false calls can occur.

A 2D AOI system can be configured for a wide variety of applications. The CyberOptics QX250i machine, for example, supports PCB sizes ranging from 50 x 50 mm to 400 x 308 mm. It also features an 80-megapixel sensor on each SIM module, resulting in a high resolution of 12 mm and a scan speed of 110 cm/sec. The QX250i system is also energy-efficient and low-cost, with a low power consumption.


The 3D Automated Optical Inspection (AOI) Equipment market is expected to expand at a steady pace between the years 2021 and 2028. Key players in the market are adopting various strategies to capitalize on this growing market. This report analyzes the global 3D AOI market through various segments, including type, application, and geography.

3D AOI systems provide companies with excellent image quality and measurement accuracy. They are scalable and can support high production volumes. These systems can be programmed easily, are easy to use and offer an extremely versatile system. Many systems also come with lighting and motion control. These systems are an integral part of quality control in electronics manufacturing.

The panel display industry is another area that is driving the growth of 3D AOI systems. This technology is capable of detecting minute defects in products. Rapid technological advancements have also made these systems more accurate and efficient, which is driving their increasing adoption by manufacturers worldwide.
