I. The basic principle of SMT X-ray machine inspection
SMT X-ray inspection equipment utilizes the penetrating properties of X-ray to scan and image the inside of the product to detect internal defects such as cracks, foreign objects, false soldering, etc. X-ray can penetrate the object and form an image on the detector, thus revealing the structure and defects inside the object. This non-destructive inspection method is especially suitable for detecting the internal condition of electronic components.
II. Application Scenarios of X-ray Inspection
1. Welding quality inspection
X-ray inspection equipment through the penetration of X-ray, can detect the soldering process generated by the false soldering, false soldering and other undesirable conditions, to ensure the quality of soldering. This is particularly important for the detection of hidden solder joints such as BGA (ball grid array package) and CSP (chip size package), because the location of the solder joints of these devices is hidden, and it is difficult to cover the traditional means of detection, and X-ray can comprehensively and accurately detect the welding quality of these solder joints.
2. Defect detection
X-ray inspection equipment defect detection coverage of up to 98%, especially for BGA, CSP and other solder joints hidden device detection. Through the image formed by X-ray penetration, it can reveal the internal structure and defects of the object, such as cracks, foreign objects, etc., so as to detect the quality of the material in advance, avoid the defective material from entering the production line, reduce the rework, and save manpower and material resources.
3. Internal Structure Inspection
X-ray inspection equipment can also detect the connection status between components on chip packages and PCB circuit boards, detect and eliminate welding defects in time, and ensure the quality of SMT placement.3 In addition, it can be used for internal structure inspection in the fields of multilayer circuit boards, circuit board assemblies, lithium-ion batteries, and semiconductor packaging.
4. Non-destructive testing
X-ray inspection equipment is non-destructive and suitable for non-destructive testing of various electronic components and assemblies. For example, in the field of automotive parts, aluminum alloy die casting, hardware products, etc., X-ray inspection can be used for perspective observation and measurement of the internal structure, to find problems and confirm whether qualified.
III. The advantages of SMT X-ray inspection
1. High precision
X-ray inspection has a very high precision, can find some small defects and problems. At the same time, because of its non-contact detection method, will not produce any damage to the welding point, so you can ensure the quality of the product.
2. Fast and efficient
X-ray inspection is fast and efficient. In the production line, X-ray inspection equipment can quickly inspect the welded joints and output the inspection results, thus ensuring the stability and efficiency of the production line.
3. Visualization
X-ray inspection can present the internal structure of the welded joints in the form of images, so as to determine whether there is a quality problem more intuitively. At the same time, X-ray inspection can also be carried out on multiple welding points at the same time to improve the inspection efficiency.
