For the new man just engaged in SMT industry, there may be some confusion between AOI machine and X-ray inspection machine. Although the basic principle of these two equipment is through the reflection of light, the component is installed correctly, the position is good and there is no leakage and other phenomena to check, but in fact the two are still very different. Let's briefly analyze their main principles and differences.
AOI stands for "Automatic Optical Inspection". Using the optical principle, the camera on the equipment scans the PCB board, collects the image, and compares the collected solder spot data with the qualified data in the machine database. After image processing, marking, can save manpower, reduce labor costs, increase efficiency.
X-ray equipment’s principle is that under the premise of not damaging the detected object, through X-ray to penetrate the object, such as BGA component welding is good and there is no short circuit detection.
The main difference between the two is that the basic principle of AOI is to check whether the component mounting is correct through the reflection of light and detect the plane of the product. And X-ray detection is the internal product, such as lithium batteries, IC chips and other products have short circuit, empty welding, welding and other defects. X-ray detection equipment is more convenient, higher detection accuracy. As a result, X-ray testing equipment has become the primary choice for more and more SMT companies.
