Optical inspection is a method of inspection on defects in targets under test by comparing images of targets under test obtained through optical imaging (after processed and analyzed with specific processing algorithm) with images of standard templates. Broadly speaking, automated optical inspection (AOI), automated X-ray inspection (AXI) and automated visual inspection (AVI) all fall into the category of AOI. The main optical inspection products available in the market now are AOI ones, and few are AXI ones. Fewer companies engage in the manufacturing of AVI products.
Currently, AOI is chiefly applied to PCB and TFT-LCD industries. However, for China, the penetration of AOI in the two industries is still rather low, with only 20%-30% of production lines in PCB industry equipped with AOI. Some companies have developed AOI products applied to semiconductor, touch panel, LED and solar cell industries. Market demands for AOI in the future will come mainly from the following three aspects: new projects in PCB and TFL-LCD industries; production lines that have not been equipped with AOI in PCB ad TFT-LCD industries, and other industries.
Globally, AOI companies with higher market share converge in Israel, Japan and South Korea, all of which have China as their key foreign market. The world’s top 5 companies by AOI revenue in 2013 were Orbotech (Israel), Omron (Japan), KohYoung Technology (South Korea), Camtek (Israel) and Screen (Japan).
In the Chinese AOI market, no company in China could manufacture AOI equipment before the year 2004, and the equipment was imported mainly from Israel, Japan, South Korea and Taiwan. From May, 2004 when the predecessor AOI R&D team of ALeader developed China’s first set of AOI, more and more AOI companies have been established to engage in the R&D, production and sales of AOI equipment. Hence, the Chinese AOI equipment manufacturers were set up after the year 2005 and distributed mainly in regions that have advanced electronic information industry, like Pearl River Delta led by Shenzhen, Yangtze River Delta led by Shanghai, and Bohai Bay Rim led by Beijing. For now, the Chinese AOI manufacturers produce mainly AOI equipment for PCB. In industries other than PCB, like TFT-LCD, IC, LED, solar cell, localization rate of AOI equipment is extremely low, almost totally dependent on import.
At present, foreign brands occupy more than 60% of the Chinese AOI market. These companies have powerful strength in technology R&D and their products feature high stability, reliability and fast speed. Accordingly, the unit prices are generally several time to ten times of that of China-made products. In 2013, foreign companies holding fairly high share in the Chinese AOI market were Orbotech, TRI, Omron and Camtek. Among local Chinese companies, Aleader (formally set up in Aug. 2005), Jutze Intelligence (established in Nov. 2007), Ekt-Tech (founded in May 2006), Zhenhua Xing Technology (set up in Feb. 2007), Zhejiang Ovi Technology (founded in Nov. 2008) and Shenzhen JT Automation Equipment (entered AOI market by acquiring Shenzhen Winning Software in Aug. 2009) are the Chinese companies with higher market share and strong R&D strength.
