摘要
An X-ray inspection apparatus and method in which an object to be inspected is irradiated with characteristic X-rays containing at least one wavelength which affords a high X-ray absorbance in the object to be inspected. A transmitted X-ray image which has passed through the object to be inspected is detected, and the object to be inspected is inspected on the basis of the transmitted X-ray image. The method and apparatus are utilized to fabricate a multi-layer printed circuit board.
