Automated Optical Inspection Market Size, Share & Industry Trends

Automated Optical Inspection Market Overview

Automated Optical Inspection Market size is projected to reach USD 2,605.52 Million by 2028 from an estimated USD 651.43 Million in 2021, growing at a CAGR of 21.9% globally.

Automated optical inspection (AOI) is an automated visual inspection method used primarily for testing printed circuit board (PCB) defects. These systems test and evaluate PCBs to detect defects such as solder defects, component defects, ball grid arrays (BGA), surface defects, dimensional defects, component placement defects, and chip-scale packaging (CSP) defects. With the advent of miniature electronics and advances in printed circuit boards, circuits have become more complex, making a manual inspection of boards almost impossible. Therefore, AOI plays an important role in inspecting these boards. Keeping costs as low as possible helps you achieve the desired product quality on your production line. This system is superior to manual inspection and takes less time. The AOI market has grown significantly in the past due to increasing demand for AOI systems in the consumer electronics, automotive, and industrial electronics sectors.

Market Dynamics And Factors For Automated Optical Inspection Market


The COVID19 pandemic has significantly shifted the world to remote work and learning in 2020. With this change, consumers have had a hard time getting devices that can be conveniently operated anywhere, such as phones, computers, monitors, microphones, keyboards, mice, cameras, and even smart coffee makers and digital foot massagers. Banned in most of the world in 2019 and 2020, after spending a long day working and studying at home, the only option people decided was to relax and play. Manufacturers want consumers to spend their hard-earned cash on flashy toys to see, hear, and play indoors. TVs, speakers, personal audio, gaming PCs and peripherals, and consoles make consumers feel comfortable at home. Homes should be more comfortable as people who spend most of their time indoors are investing more in technology upgrades. This has further increased the demand for innovative home appliances.

Demand for sophisticated home appliances and devices is increasing due to factors such as an increase in urban population and an increase in disposable income. At the same time, consumers want high-quality products that are affordable, durable, and durable. As the demand for household appliances grows exponentially, electronics manufacturing facilities are being built around the world. The growing demand for better products has led PCB manufacturers to invest in manufacturing processes and make them more economical. Therefore, to improve product quality and make production more economical, circuit board manufacturers use AOI systems on their production lines. The AOI system replaces manual inspection of PCBs, enabling faster and more accurate defect detection and accelerating overall production cycle times to help PCB manufacturers improve their quality processes. The AOI system has evolved. With the shrinking size of printed circuit boards and the advent of advanced technology in electronics, a manual inspection is no longer a viable option, increasing the need for AOI systems.

Automated optical inspection is regarded by the majority of the electronics industry as a reliable inspection process for printed circuit boards. The penetration of powerful technology in the consumer electronics sector is driving the growth of the global AOI market.


The false call rate is defined as the number of good parts identified as defective, and the number of parts per million is a measure of the false call rate. When considering an image-based AOI system, false calls are the most important factor. Image-based AOI systems use a set of images to isolate defective components from good components. At the same time, the system primarily relies on operators to capture these images and feed them into the database. Images that are misclassified may be included in the image database, making parameter optimization impossible. If an image containing defective components is placed in the “good” part of the image based, the optimization process may adjust the parameters of the AOI algorithm that classified the image as “good”. As a result, the system cannot detect this specified error. This can indicate a false call that can cause a serious inspection disaster. In addition, the wrong call requires the operator to check for errors and repeat the process, resulting in slower manufacturing processes, lower productivity, and higher manufacturing costs.


Self-Monitoring, Analysis, and Reporting Technology (SMART), as the name implies, has revolutionized the outlook for technology with the advent of intelligent technology. From smart devices such as smartphones, smart watches, and laptops to a wider range of applications in smart homes and smart factories, smart technology is becoming increasingly widespread.

Smart technologies include a variety of devices such as IoT devices and smart connected devices. IoT devices are a network of devices that use sensors, chips, software, online connections, analytics, and applications to bring static physical objects to life. These devices create great value and are futuristic, scalable, and automated. Some prominent examples are smart cities, smart homes, and smart factories. Smart-connected devices are controlled via remote control and connected via the Internet or Bluetooth. Intelligently networked devices can provide a personalized experience but must be operated using remote controls. Smart security cameras, smart light bulbs, and smartphones are examples of smart connected devices.  The manufacturing process for basic components such as PCBs and integrated circuits (ICs) that make up

Smart devices are also evolving. With the increasing demand for smaller, more sophisticated devices, PCBs with complex multitier architectures are becoming even smaller. The trend toward smaller sizes has allowed manufacturers to increase the number of components mounted on their circuit boards. The need to quickly and reliably check all components is driving the demand for AOI systems.  AOI systems play an important role in the inspection of compact circuit boards. In this way, the AOI system guarantees error-free production of printed circuit boards and reduces electronics malfunction.


The latest AOI systems are highly developed for the current harsh conditions of the electronics manufacturing ecosystem. The miniaturization of electronic components and the increasing complexity of PCB architectures mean that AOI systems have evolved. Multiple high-resolution cameras are used in today’s AOI systems to capture more detailed images of complex circuit boards. These new cameras can reach over 120 frames per second (fps). High-resolution images and fast scan rates produce a significant amount of data. Enterprises need to maintain sophisticated hardware systems and software solutions to store and process this vast amount of data. Not all electronics manufacturers can maintain such an expensive support system. This is a challenge for the growth of the AOI system market.

COVID-19 Impact on Automated Optical Inspection Market

In the COVID 19 situation, the growth of the AOI market is expected to slow as pandemics limit the supply and deployment of hardware components such as sensors in many applications. This is due to the serious turmoil in business and the global economy. However, not all semiconductor companies are experiencing a slowdown in growth. Working from home in remote areas allows businesses to continue working during the blockade. In the current COVID 19 crisis, some companies face short-term operational problems due to the limited availability of the workforce through the government’s social distance protocol. Many companies whose fiscal year ended in March 2020 were affected by COVID 19.
