Several precautions for X-RAY detection chips

X-RAY detection equipment is a type of equipment that uses X-ray penetration to detect non-transparent objects. As a very important component in the current electronic industry chain, chips have received crucial attention, especially after the outbreak of the Sino US trade war, the strategic significance of chips has been brought to an unprecedented level. Chips are mainly divided into three parts: design, manufacturing, and testing. The most difficult part is manufacturing, which is also the core area of the current bottleneck. JEENOCE mainly introduces the precautions for X-RAY detection of internal abnormalities in chips, generally including the following points:

1. Understanding chip structure: Before conducting X-RAY testing, it is necessary to fully understand the internal structure of the chip, including the positions and connection methods of various components. This helps to identify areas that need to be detected and potential anomalies.

2. Select the appropriate X-RAY device: Select the appropriate X-RAY device based on the type and structure of the chip to be tested. Different devices have different resolutions and penetration capabilities, and they need to be selected based on actual situations.

3. Adjust X-RAY parameters: The parameters of the X-RAY device need to be adjusted based on the type and thickness of the chip. If the parameters are set improperly, it may lead to undetectable or misjudgment of anomalies. Therefore, before conducting testing, it is necessary to carefully adjust the parameters.

4. Determine the detection angle: During X-RAY detection, different angles may lead to different results. Therefore, it is necessary to choose an appropriate angle for testing. Generally speaking, the angle perpendicular to the chip surface is the most commonly used detection angle.

5. Pay attention to detection details: When conducting X-RAY detection, it is necessary to pay attention to details. For example, it is necessary to ensure that the chip surface is clean and free of impurities to avoid interfering with the detection results. In addition, it is necessary to ensure that the distance and angle between the X-RAY device and the chip are accurate and accurate.

6. Combining with other detection methods: Although X-RAY detection is a very effective detection method, it also has its limitations. Therefore, it is necessary to combine other detection methods, such as SEM, EDS, etc., to conduct more comprehensive detection and analysis of the chip.

7. Professional operators: X-RAY testing is a highly technical testing method that needs to be carried out by professional operators. Operators need to have rich experience and professional knowledge to ensure the accuracy and reliability of testing results.

In summary, there are multiple issues that need to be addressed when X-RAY detects internal abnormalities in the chip. Only by fully understanding the structure and characteristics of the chip, selecting appropriate equipment and technical parameters, can the accuracy and reliability of the detection results be ensured. At the same time, it is also necessary to combine analysis with other detection methods to obtain more comprehensive detection results.
