Inspection is a critical component of the electronics manufacturing industry, aimed at ensuring the quality, reliability, and safety of electronic components and devices throughout the production process. Inspection involves a range of techniques and technologies, including optical and X-ray imaging, as well as other advanced imaging and sensing techniques.

Optical inspection techniques, such as visual inspection and automated optical inspection (AOI), use cameras and other imaging devices to inspect electronic components and devices for defects, such as missing components, misaligned pins, and soldering defects. These techniques are particularly effective for inspecting surface-mounted devices (SMDs) and other components with visible features.
