Growing Demand for Automated Optical Inspection Systems during (2020-2026)

Global automated optical inspection system market size is estimated to be USD 646 million in 2021 and projected to reach USD 1,660 million by 2026, at a CAGR of 20.8%.

The rising demand for higher productivity by electronics manufacturing services (EMS) companies and growing demand for electronics in automotive sector is driving the growth of the automated optical inspection system market. Moreover, the emergence of smart technology as well as utilization of AOI system in newer applications is alsoexpected to drive the growth of the market in the near future.

An AOI system works efficiently while inspecting PCBs where solder joints are visible. However, with the advent of new PCB and IC manufacturing technology such as ball grid array (BGA), where solder joints are not visible, AOI systems are not capable of finding soldering defects.

3DAOI systems inspectassembled PCBs and other electronics in three dimensions. This is in contrast to2D AOIsystems. 3D AOI system typically uses a camera to verify that the items meet quality standards, making sure they are of the right size or their proper locations.3D AOI technology has emerged as a viable technology for the detection of a variety of manufacturing defects. A 3D AOI system is used where there is a requirement for more rigorous standards for surface mount devices (SMDs), and high precision for defect detection is required. Thus, 3D AOI system market is expected to be dominant during the forecast period.

Inline AOI systems are a valuable part of the manufacturing workstation process. Inline AOI is part of the production line and is more suitable for inspecting components on a fast-moving production line. In an inline AOI technology, the boards are loaded and unloaded automatically, making the inspection of PCBs faster. Inline AOI systems can be strategically placed before or after the reflow process, depending on the requirements of manufacturers. Hence, most of the large manufacturing companies install multiple inline AOI systems in their production lines to speed up the inspection process.

The growing share of advanced electronics to support various functionalities of automobiles is expected to boost the AOI system market for automotive. The industry needs critical inspection of PCBs to ensure consumer safety and reliable working of the vehicle. AOI, conformal coating, and solder paste inspection offer non-invasive inspection solutions, providing real-time process data for accurate detection of faults and improvement in yield.The advent of new technologies such as autonomous driving, connected vehicles, electric vehicles, automotive sensors, and advanced navigation and infotainment systems has increased the share of electronics in automobiles to a higher level. There is rising adoption of Industrial IoT (IIoT) in the automotive sector.
