AXI machines (Automated X-ray Inspection Machine) are automated inspection devices used in electronics manufacturing, especially in SMT (Surface Mount Technology) and PCBA (Printed Circuit Board Assembly). AXI machines use X-ray imaging technology to inspect the solder quality, component placement, and integrity of circuit connections inside the circuit board, detecting defects that cannot be seen on the surface, such as cold solder joints, short circuits, cracks, voids, etc.
AXI machines scan the PCBA using an X-ray source. The X-rays penetrate the circuit board and are absorbed to varying degrees based on the density differences of different materials.
After passing through the circuit board, the X-rays are received by a detector and generate an image. The image shows the internal structure of the circuit board, and detected defects such as bubbles, voids, and bridges will be presented in different ways.
AXI machines can automatically analyze the images through built-in software, identify potential defects, and classify and mark them, helping operators quickly locate problem areas.
The AXI inspection method does not cause any damage to the product, making it suitable for high-value, high-precision electronic products.
AXI can detect internal defects that traditional optical inspection methods cannot find, especially for components with dense surface packaging such as BGAs (Ball Grid Array), effectively inspecting their solder joint quality.
AXI equipment can provide high-resolution images, and the automated inspection process can significantly improve inspection efficiency, reduce manual intervention, and increase production line capacity.
Widely used in the production process of electronic products, particularly in PCBA production, BGA soldering, chip packaging, etc., to ensure the reliability of solder quality and circuit connections.
For high-end products in these industries, AXI machines are also used to ensure the safety and quality of components and circuits.
As an advanced inspection tool, AXI machines play a crucial role in modern electronics manufacturing, particularly in improving product quality, reducing defect rates, and ensuring production efficiency. With continuous technological advancements, the inspection accuracy and application fields of AXI machines are constantly expanding.
