With the continuous development of electronic devices towards miniaturization, intelligence and high performance, the demand for patch components is increasing.

In addition, with the rapid development of electronic technology, new types of patch components are emerging, and their structures and performances are becoming more and more complex, which puts higher requirements on the detection and quality control of patch components. Traditional detection methods and equipment often cannot adapt to the characteristics of new patch components and cannot meet the needs of fast, accurate and comprehensive detection.
