Automated Image Sensor Package Testing Before Camera Module Assembly

The patent implements preliminary testing of image sensor packages before they are assembled into camera modules. The testing apparatus includes a seating unit that holds multiple image sensor packages, a light source that irradiates the packages, a lens that focuses the light, and a sensor that detects the converted electrical signals. This preliminary action allows defects to be detected early, preventing defective packages from being assembled, thereby maintaining high productivity while ensuring reliability.

The patent implements an automated testing system where the apparatus itself performs all testing operations without manual intervention. The seating unit automatically positions multiple image sensor packages, the light source automatically irradiates them, the lens automatically focuses the light, and the sensor automatically detects the signals. This self-service automation eliminates dust and moisture introduction while maintaining testing flexibility through programmable control, thereby significantly increasing productivity.

The patent designs a universal testing apparatus that can test multiple image sensor packages simultaneously. The seating unit is configured to hold multiple packages, the light source irradiates all packages, the lens focuses light on all sensors, and the sensor array detects signals from all packages in parallel. This multi-functionality reduces the need for multiple separate testing stations, thereby reducing overall system complexity while maintaining high reliability through pre-assembly testing.
