3D AOI systems to account for a larger share of the automated optical inspection market

The 3D AOI system market is expected to be dominant and faster during the forecast period. Large-scale manufacturing units primarily make use of 3D AOI systems. 3D AOI systems have high operational costs and use complex programming codes for functioning but are more efficient and sensitive at detecting defects and faults than 2D AOI systems. 3D AOI systems can detect faults in PCB substrates as well as in the ball grid array (BGA), which makes them superior to 2D AOI systems. Further, the ability to quickly inspect defects in tall components, significant reduction in false call rates, and ability to provide volumetric data of components under inspection make 3D AOI systems an ideal choice for electronic manufacturing service (EMS) providers in the coming years.

Consumer electronics industry accounted for the largest share of the automated optical inspection market in 2020

The consumer electronics segment is expected to hold the largest share of the AOI system market during the forecast period. The miniaturization of electronic gadgets has further increased the complexity of internal circuits and components. To efficiently inspect complex PCBs of small and compact consumer electronic devices, manufacturers are increasingly using advanced AOI systems to offer high-quality products to customers. The trend of having one device with multiple functionalities has made modern-day electronic devices such as smartphones, laptops, and wearables more complex in architecture. The increased complexity of these devices requires highly advanced AOI systems for inspection. Further, with the rise in the adoption of 3D inspection technology, AOI systems are going to play a vital role in maintaining the high-quality standards of these complex consumer electronic devices.

Asia Pacific to account for the largest share of the automated optical inspection market by 2026

APAC is the leading region for global PCB production, with countries such as China, Taiwan, Japan, and South Korea at the forefront. The increase in high-volume manufacturing of PCBs creates a demand for AOI systems with faster inspection speed. The APAC electronics industry has become a world-class innovation-driven hub for production as a result of low-priced skilled labor, business-friendly environment, low production cost, and growing demand for electronic products in the region. The growth in the electronics industry has enabled the APAC AOI market to grow at a significant rate.
