Claim 0:
1. A chip counter configured to count semiconductor chips (5) mounted on a tape (4) wound onto a tape reel (1) by placing the tape reel (1) on a plurality of test beds (30 and 40), the chip counter comprising:
a sealed housing containing
the tape reel;
the plurality of test beds;
a fluorescent intensifying screen;
an X-ray tube configured to transmit an X-ray beam through the tape reel which reacts with the fluorescent intensifying screen;
a camera positioned behind the fluorescent intensifying screen and configured to obtain an image by detecting the X-ray beam that is transmitted through the tape reel and fluorescent intensifying screen; and
an X-ray shielding member that blocks the X-ray beam directed to the camera, wherein the plurality of test beds are arranged between the X-ray tube and the fluorescent intensifying screen, and wherein the X-ray tube and the camera are configured to obtain an image; and
a computer configured to receive and image-process the image.
