What is Automated Optical Inspection

Automated optical inspection (AOI) is an automated visual inspection of printed circuit board (PCB). AOI scans the PCB find out both catastrophic failure (e.g. missing component) and quality defects (e.g. fillet size or shape or component skew). Meanwhile, it is a non-contact test method. It is implemented at many stages through the manufacturing process including bare board inspection, solder paste inspection (SPI), pre-reflow and post-reflow as well as other stages. Automatic optical inspection enables fast and accurate inspection of electronics assemblies and in particular PCBs. Therefore, the AOI test is not so costly and time consuming as the other mentioned test procedures.

Automated Optical Inspection (AOI) market analyzed by product type

  • Inline AOI 

In-Line AOI using a high performance line-scan technology. The board is loaded and unloaded using SMEMA conveyor the software uses optical alignment to on-board fiducials maintaining positional accuracy from board to board.

  • Offline AOI 

Offline programming and debug is made easy as ScanSpection software allows the actual board for test or debug to be saved in a TIFF format. The saved images and software are exactly the same as ScanSpections, making program creation and updates easy without impacting on the production schedule. 


Key Players in AOI market

Orbotech, Camtek, Koh Young, Omron, Screen, Nordson, Wuhan Jingce, 3i System and ZhenHuaXing are the major international players in the market of AOI. The reasons are their production technological advantages, their long-term presence in the market, the relationships they have developed with downstream users over a long period of time and the brand name recognition they enjoy.

Automated Optical Inspection (AOI) market analyzed by technology

  • 2D AOI 

In this day and age, 2D inspection technology is the most widely adapted AOI solution available to electronics manufacturers. The most advanced systems have multiple ultra-high resolution cameras, 10 to 15 Mega Pixel resolution, precision telocentric lenses and multi-tiered lighting technology to properly.

  • 3D AOI 

Although 3D inspection technology has existed for many years in the electronic inspection industry, this technology has primarily been reserved for inspecting solder paste depositions on printed circuit boards directly after the screen printing process. Over the past few years, however, 3D inspection has emerged as a viable technology form testing gull-wing and BGA devices as well as a host of other co-planarity sensitive circuitry on finished PCB assemblies. Of course, the main reason for the industry trend toward 3D inspection technology is to compensate for the limitations of conventional 2D inspection.

Recent Developments in Automated Optical Inspection (AOI) market

STI Electronics announced that it has acquired a new Nordson YESTECH FX-940 ULTRA 3D Automated Optical Inspection (AOI) system. That is to say, this new AOI system provides STI’s contract assembly services with a significant improvement in throughput with the ability to inspect 1.5 million components per hour. Consequently, the system’s accuracy rate will give customers a level of confidence far exceeding that of visual inspection or other AOI systems using older technology.
