  • Patent number: 6205238
    Abstract: Disclosed are apparatus and method for inspecting leads of an IC placed on a setting table. The apparatus comprises an optical image recognition part for scanning the setting table, a device for moving the recognition palt with respect to the setting table, a position detection palt for detecting a position of the recognition part on the basis of an output signal thereof, and a control part for controlling the device on the basis of a signal of the position detection pait so that the recognition part is positioned at an optimal position above the setting table. The setting table is scanned stepwise, and the optimal position is a position that the value of the output signal is maximized. The recognition pall is positioned at the optimal position. The arrangement and the status of the leads of the IC are inspected automatically in a short period of time, and productivity increases.
