    摘要: An apparatus and method for securing a substantially circular wafer uses a chuck having a plurality of tensioning grooves each having at least one arcuate bend having a bend radius substantially less than an outer region radius, and a vacuum source interconnected with each of the grooves. When the wafer is placed upon the surface concentric with the chuck center and the vacuum source applied to the grooves, the wafer is held securely to the surface without distortion.

    摘要: The present invention provides a method and apparatus for increasing the frame acquisition rate of an frame transfer CCD sensor by triggering the charge transfer signal TR, which controls the shift of the electrical charges from the light-sensitive cells into the vertical shift register, more than once per frame period, so that more than one image is acquired in the same frame, one above the other. The apparatus is used primarily for surface geometry inspection of high-speed moving objects, wherein acquired CCD images are thin, substantially horizontal profile lines.

    摘要: The leads of a QFP are examined by an optical system. The optical system includes a sensor head having two lasers, the outputs of the lasers being fed to a beam splitter which provides outputs at right angles to each other, and a ring-light which is disposed under the beam splitter and in actual alignment with the beam splitter. The sensor head is carried by a carriage in a single plane along two transverse directions. The carriage moves the sensor heads so as to examine one lead at a time along the peripheral edges of the QFP.

    摘要: For computing the absolute height, in a field of view of a CCD-based acquisition system, of the profile of an object moving on an assembly line, two CCD-based image acquisition devices are used. The consecutive acquired images of the two CCD-based image acquisition devices are shifted by a predefined number of lines. Using two relative heights, the absolute height of a feature located in the acquired images is computed.
