Automated X-ray inspection (AXI) is a technology based on the same principles as automated optical inspection (AOI) but it uses X-rays as its source instead of visible light to automatically. Using X-ray has two major goals:
Optimization your process, namely the results of the inspection are used to optimize following processing steps,
Abnormal detection, for example the result of the inspection serve as a criterion to reject a part (for scrap or re-work).
Whilst AOI is mainly associated with electronics manufacturing (due to widespread use in PCB manufacturing), AXI has a much wider range of applications. It ranges from the quality check of alloy wheels to the detection of voids.
