Abstract
The present invention relates to a chip counter, which transmits an X-ray beam through a tape reel around which a tape having a plurality of semiconductor chips mounted in a row therein is wound, acquires an image scattered or diffracted by the semiconductor chips, and processes the acquired image, so as to count the number of the semiconductor chips, wherein: the X-ray beam transmitted through the tape reel () is sensed by a fluorescent intensifying screen (); a fluorescent light emitted from the fluorescent intensifying screen () according to the sensing of the X-ray beam is captured by a camera (), so that the number of the semiconductor chips is counted from an image in which the semiconductor chips are displayed by a dotted image; and the camera () is protected by an X-ray beam shielding member (; and).
