Background knowledge

In the highly competitive smartphone manufacturing industry, every component must meet strict quality standards to ensure excellent performance and customer satisfaction. Among them, the camera module is one of the most critical and complex components. Ensuring that the camera module is absolutely flat is critical to avoid image distortion and get clear, high-quality images.

Traditional detection methods often rely on manual visual inspection or low-precision measurement tools, which are not only time-consuming and laborious, but also prone to errors. In contrast, the automated detection of a 3D camera can greatly improve the detection efficiency and reliability. It can complete the detection of a large number of modules in a very short time, while ensuring the consistency and accuracy of the detection results.
