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 (1) is sensed by a fluorescent intensifying screen (60); a fluorescent light emitted from the fluorescent intensifying screen (60) according to the sensing of the X-ray beam is captured by a camera (70), 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 (70) is protected by an X-ray beam shielding member (100: 110; 120; and 130).
