The main application of the method is as follows: 1) And (3) detecting an internal structure: the X-ray can penetrate through the packaging material of the integrated circuit and can be used for detecting the internal structure and connection condition of the chip. It can help to find problems of gaps, breaks, shorts, etc. of the metal lines, as well as connectivity between the component and the metal layer. 2) Welding spot and contact detection: x-ray inspection can be used to evaluate the quality of the connection of solder joints and pins in an integrated circuit package. By analyzing the X-ray projection images, it is possible to detect whether the solder joints are complete, whether the pins are inserted properly, and identify potential soldering problems such as soldering failure, offset, open circuit, etc. 3) Size and arrangement detection: x-ray detection can be used to measure and analyze the accuracy of integrated circuit dimensions, structures, and component arrangements. It can detect the size, position, shape and spacing of the elements to ensure that they meet design specifications. 4) Peeling and contamination detection: x-rays can be used to detect delamination and contamination problems in integrated circuit packages. The method can identify external impurities, particles and bubbles penetrating into the packaging material and peeling conditions among packaging layers, and ensures the integrity and reliability of packaging.
