Why do we need to use an automatic optical inspection machine?


Why do we need to use this machine for inspection even if the manual method is also required? Before jumping into depth into these machine features let’s discuss why the AOI machine is important to use. Despite the improvements that had been made, the circuit boards are getting more complex as compared to the past few years than we think. Due to this complexity in the board’s manual method is no more a viable option for the circuits. We need an advanced method for this purpose.


To deal with the complexity of the board we use an AOI machine that ensures that the costs are kept as low as possible by detecting faults early in the production line. It detects the problems and faults in the solder and assembly area very quickly. This ensures that the faults are being recognized and rectified before too many boards are built with the same problem.

The key factors affecting the cost of automatic optical inspection machines:


In this section, we are going to report on the factors that are the actual reason behind the cost of these machines. Also, we will let you know the things that you should keep in mind before purchasing this machine.


Hardware and software cost:


The software of automatic optical inspection machines consists of operating systems and the software used for the inspection process. The hardware of the AOI system consists of a recognition system, mechanism system, controller system, and so on. The different choices on hardware and software can affect the price of the automated optical inspection machine.

Things to keep in mind while purchasing this machine- A complete user guide:


Automatic optical inspection machine has become very important for the electronic manufacturing industry to ensure product quality. Therefore choosing the best and highly reliable AOI machine from many different brands has become a major issue for electronic manufacturing workers.

In this section, we are going to share some information regarding purchasing this machine. Moreover, we will also let you know the things to keep in mind while purchasing this product. So without wasting time, let’s start!


Composition of AOI:


It is very important to understand the basic structure and composition of an automatic optical inspection machine before buying it. AOI is composed of different kinds of systems that include vision systems, software systems, mechanical systems, and operating systems. All these things are the major components of the automatic inline optical inspection machine. Always check for these components before purchasing this product.



AOI’s vision system selection:

The other thing that you must keep in consideration is the selection of the vision system. The AOI’s vision system is composed of a camera and a light source.

  • The choice of a camera:
    The camera should be of the best quality as it plays a major role in detecting faults. Nowadays, in the marketplace manufacturers are using two types of cameras. These are line scan cameras and area scan cameras. The line scan camera uses the progressive scan method to capture the images. Most manufacturers in the marketplace use this type of camera for clearer images.

But the image reproducibility of the line scan camera is poor and it is difficult to adjust the angle. Therefore the best choice of camera is an area scan camera. The area scan cameras are being divided into two categories (1) analog cameras (2) digital cameras.

Analog cameras are being widely used in the manufacturing industry. Digital cameras are of great importance, and they have the advantage of good image reproducibility, which is convenient for software to analyze and process images. Regardless of its advantages, it is very expensive.


  • The choice of light source:
    The eyes of AOI are the light source. The quality of the light source is the most important thing that helps to strengthen the AOI detection capability. The light sources used for the AOI machine can be of two types (1) ordinary fluorescent lamps and (2) coaxial. Ordinary fluorescent lamps use line scan cameras. We have already discussed that these cameras are not the best choice.

    The coaxial light source is divided into two types- color coaxial light sources and monochromatic light sources. The color coaxial is the right choice because the image obtained by it is more realistic.


The choice of motor:

The motors that are being used by AOI machines are linear, servo motors, and stepping motors. The most commonly used motors by the manufacturers are servo and stepping motors. The accuracy of linear motors is very high.

After linear motors, servo motors have high accuracy. But, if we talk about the stepping motors, they have very high accuracy as compared to the other two motors. The selection of motors should be based on the cost-effective method. Therefore if you don’t want to compromise on the accuracy, but also you have a tight budget, then go for the servo motors.


The software:

The software environment is very important for AOI’s program to control. Before buying the machine, it is important to know in which programming language the software is developed. According to actual work experience, the software developed in the C++ language is highly stable and reliable. C++ is very close to the machine, and it is processed quickly. So, going for the Windows operating system would be a good choice because it is developed in C/C++.



CNSMT automatic optical inspection machine detects the faults and problems in PCB very quickly. It has replaced the use of the manual method and now all the manufacturers are using the automatic method for complex components.


There is no doubt that the manual method is good, but due to increasing complexity in the PCB assemblies, a manual method is no more a better option. The CNSMT AOI machine comes up with several different features that include the highly imported camera, x-y platform, and so on.


It has a light source that consists of three different color lights present in the form of a ring. It is very easy to operate as the keyboard system is available in two different languages. So, if you want to bring innovation to your business, then going for this product will be a great choice for you.



What is an Automatic optical inspection machine?


An automatic optical inspection machine, which is also abbreviated as AOI is used to detect errors and faults from the PCB with great efficiency and accuracy. It is the replacement of manual inspection where you have to sit at a place and have to inspect each part of the board one by one. With the invention of the automatic optical inspection machine, the work has become easier for the manufacturers.


Why we should use an AOI machine?


The marketplace is producing products that are highly complex to handle and difficult to get inspected. The manual method is not now viable for these types of complex products. That’s why we have to use the AOI method that detects the error more quickly.
