Apparatus for judging whether bump height is proper or not

Image Number 13 for United States Patent #6437355.

An apparatus to check a height of a bump includes a measuring device and a determining device. The measuring device is configured to measure a distance between an image position in an image of a reference object reflected in a surface of the bump and a predetermined position which is positioned on a line connecting the image position and a center of the bump such that the image position exists between the center and the predetermined position. The determining device is configured to determine whether the height of the bump is within a predetermined range by comparing the distance with a reference distance.
