The quality of the circuit board directly affects the performance and reliability of the product. Therefore, quality inspection of circuit boards has become particularly important. X-ray inspection, as a non-destructive testing technique, can deeply observe the internal structure of circuit boards and plays a crucial role in the production and testing process.
Application of X-ray Inspection Machine in Circuit Board Inspection
The X-ray inspection machine emits X-rays that penetrate the circuit board, and the transmitted image information is received by the detector and converted into image data, which can clearly present the structural details inside the circuit board. X-ray inspection equipment can not only detect surface problems on circuit boards, but also deeply identify internal defects and anomalies. For example, issues such as poor welding, missing components, and broken circuits can be accurately captured and located through X-ray detection equipment.
During the inspection process, the circuit board to be tested needs to be placed in the inspection area of the X-ray inspection equipment. The operator will set appropriate detection parameters, including X-ray energy, detection angle, scanning speed, etc. After the device is started, X-rays will penetrate the circuit board, and the detector will convert it into high-definition images. These images provide analysts with rich details that help discover small defects and anomalies.
Key functions of X-ray detection equipment
1. High precision detection
X-ray detection equipment has extremely high sensitivity and resolution, and can identify tiny defects inside circuit boards. For example, in the detection of welding points, X-ray inspection equipment can identify whether the welding quality meets the standards and detect points where the tin penetration rate does not meet the standards. Normally, points with a tin penetration rate below 70% are considered unqualified and require further repair or replacement.
2. Fully automated testing
Modern X-ray inspection equipment has CNC automatic programming function, which can achieve fully automatic inspection. This automated detection greatly improves detection efficiency while reducing the risk of human error. During the detection process, the equipment can accurately capture the points of the circuit board with unqualified tin penetration rate through programmed parameters, and mark the abnormal areas on the screen with red dots for easy identification and handling by the detection personnel.
3. Real time analysis and feedback
X-ray detection equipment can not only quickly scan circuit boards, but also analyze and provide real-time feedback on detection results. This is particularly important for manufacturers, as they can immediately carry out quality control and adjust production processes based on test results, thereby significantly reducing the rate of defective products and improving product consistency and reliability.
Advantages of X-ray detection equipment
1. Non destructive testing
Unlike traditional detection methods, X-ray detection does not require disassembling the circuit board or damaging its structure, and can perform detection without affecting the integrity of the circuit board. This non-destructive testing method not only protects the test samples, but also significantly reduces testing time and costs.
2. Multi angle and all-round detection
The X-ray detection equipment can flexibly adjust the detection angle to achieve observation of various angles of the circuit board. This multi angle detection function can ensure comprehensive detection coverage, thereby discovering potential defects that may be overlooked at a single angle.
3. Precise identification of minor defects
For modern high-density circuit board designs, even minor soldering defects or missing components can have a significant impact on overall functionality. Due to its high sensitivity, X-ray detection equipment can amplify and capture these subtle issues, ensuring that the product reaches its optimal state before leaving the factory.
The practical application of X-ray detection equipment in circuit board production and maintenance
X-ray detection equipment is widely used in the manufacturing and maintenance of circuit boards. During the manufacturing process, X-ray inspection equipment can perform quality control on circuit boards at each production stage, enabling timely detection and repair of problems, reducing defect rates, and ensuring product consistency and stability. In the maintenance process, X-ray detection equipment can help technicians quickly locate the fault point of the circuit board, improve maintenance efficiency, and reduce customer waiting time.
The application of X-ray detection equipment in circuit board inspection undoubtedly provides strong support for electronic manufacturers and maintenance technicians. It not only allows non-destructive testing inside the circuit board, but also has the advantages of high precision, full automation, and multi angle testing, making circuit board quality control more efficient and accurate. Through X-ray detection equipment, enterprises can better ensure product quality and enhance market competitiveness.
