What Is Automated Optical Inspection Machine?

Automated optical inspection (AOI) is an automated visual inspection of printed circuit board (PCB) (or LCD, transistor) manufacture where a camera autonomously scans the device under test for both catastrophic failure (e.g. missing component) and quality defects (e.g. fillet size or shape or component skew). It is commonly used in the manufacturing process because 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.

In the context of manufacturing and technology today, which is highly competitive and aware of the costs faced by companies today, it is necessary to learn to balance quality with speed and through automation is the key to success and achieves an increase in quality. This is why it was created, automated optical inspection which will help meet the demand to reduce costs, while maintaining the highest possible quality.

With unrivaled experience in the field of automated optical inspection and the most powerful inspection systems and software systems available, you will discover the advantages of automation. This is why the Sipotek Company offers a complete line of automated optical inspection solutions, which gives your company the necessary tools to monitor its manufacturing processes and significantly improve overall quality.

But what is really this system, this system consists of a visual inspection that is carried out in an automated way on a wide range of products, such as transducers, automotive applications, fruit and vegetable seeds, LCDs, diverse circuits and product packaging labels of agricultural.

But as this machine can do that they will ask, because the machine has an automatic camera that scans the device in the form of a test and detects defects such as spots, scratches, and also between open circuit and closed circuit. In the same way this automated optical inspection detects missing parts and incorrect components, as well as badly placed ones if the machine was adjusted for agricultural work, it is able to differentiate between colors and fruits made to lose



  • Can perform the work performed by a human operator with greater efficiency and speed
  • Avoid human errors and operator negligence
  • It can classify at a higher speed
  • It is a practical equipment to use
  • Human inspection may not be stable and may be affected by many variables. An automated optical inspection not only standardizes the process, but also reduces the inspection time and the cost of maintenance, and increases the capacity and quality of manufacturing.
  • Automated optical inspection equipment detects the following defects in welding components and joints. Component: Missing, Recessed, Bidirectional Flat Radiation, Polarity, Bias, Marking, Defective Weld Board: Over / Under Weld, Short, Through Holes, Raised Cable, Notorious Burrs. Evidencing the large number of errors that can detect that perhaps the human is not


The Sipotek team designs automated optical inspection machines, equipped with an easy-to-use operator interface and with an acquisition of accurate and maximized surface images.


These machines are developed to detect defects, as well as allow a classification between the objects by color, shape and by other different variations. They are also designed to identify cuts, breaks and profile defects. It works with a wide range of materials, from plastic to organic products, from glass to textiles.


All this can be done by an automated optical inspection machine in just a few minutes and as mentioned above, reduces operator errors in this task. The Sipotek team has a wide variety of automated optical inspection machines, which you can check on your website and find out which machine is best suited to your needs
