What is SMT X-RAY

X-RAY is a technology that uses the penetrating power of X-rays to perform non-destructive testing on the internal structure of PCBA. This technology is mainly used to detect the internal structure and defects of electronic components, connectors, etc., such as solder joint quality, internal cracks, voids, etc.

How many types of SMT Automated X-RAY inspection PCB are there?

SMT X-RAY mainly has two types: two-dimensional X-RAY and three-dimensional X-RAY.

Two-dimensional X-RAY can only provide a positive view from top to bottom, which is suitable for basic defect detection, such as checking solder joint thickness, shape and mass density distribution. This type of X-RAY equipment has a relatively simple structure and a fast detection speed, but its functions are relatively limited.

Three-dimensional X-RAY can perform three-dimensional imaging reconstruction, using X-ray tomography, X-ray layering or computed tomography (CT) to obtain a complete three-dimensional effect. This type of X-RAY is suitable for more complex detection needs, such as a comprehensive analysis of BGA soldering defects, but the detection speed is slow and the cost is high.

In addition, according to different usage scenarios, X-RAY detection equipment can also be divided into offline and online types. Offline X-RAY requires manual operation to pick up and place materials and scan and label, while online X-RAY has functions such as automatic scanning, labeling, and sorting defective products, which can maximize work efficiency and save labor.

Main functions of X-RAY

The main functions of X-RAY equipment include solder joint detection, component detection, PCB board detection, and package detection. X-RAY equipment can detect the position, size, and integrity of solder joints through the penetration of X-rays to ensure the quality of welding.

In SMT production, X-RAY equipment is mainly used to detect hidden solder joints, such as the welding quality of components such as BGA and CSP. These solder joints are hidden and cannot be directly observed by the naked eye or traditional AOI equipment. X-RAY equipment can see through these hidden solder joints to ensure that there are no welding defects such as cold solder joints and bridging.

What are the precautions for SMT PCB X-RAY inspection?

1. 1. Radiation safety: X-rays have radiation hazards. When operating, they must be strictly in accordance with the official usage rules and equipment indicator lights to ensure the safety of operators1.

2. 2. Equipment power safety: Ensure that the input power supply of the equipment is of standard voltage to avoid equipment damage or safety accidents caused by unstable voltage1.

3. 3. Equipment maintenance: Regularly check the integrity of each component of the equipment, especially the maintenance of X-ray tubes and detectors, to ensure the normal operation of the equipment and extend its service life.

What are the consequences of improper maintenance of SMT X-RAY inspection for electronic components?

1. Equipment performance degradation: As the use time increases, the performance of the equipment may decline. If regular maintenance and calibration are not performed, the risk of missed detection and false detection may increase.

2. Missed detection and false detection: Insufficient equipment resolution, image processing and analysis errors, insufficient operator experience and training, etc. can all lead to missed detection and false detection1.

3. Safety hazards: Equipment aging and improper maintenance may cause equipment failure, increase operating risks, and even cause harm to operators.

Are there any preventive measures for improper maintenance?

1. Regular maintenance and calibration: Regularly maintain and calibrate the equipment to ensure stable equipment performance.

2. Train operators: Provide professional training to operators to improve their ability to recognize and interpret X-ray images.

3. Use high-quality solder paste: Choose high-quality solder paste to ensure that its validity period and viscosity meet the requirements.

4. Adjust the parameters of the placement machine: Regularly check the air pressure and other parameters of the placement machine to ensure the placement accuracy.
