わせ装置。 a first visual sensor that non-contactly scans the lead portion of the quad flatpack IC from below; a second visual sensor that is disposed perpendicular to the first visual sensor and non-contactly scans the lead from the side; a sensor input means for inputting signals from the first visual sensor and the second visual sensor, and determining the number of leads on one side of the quad flat pack IC based on the data input from the first visual sensor. The center value of one side is calculated from the center value of each lead, and the center position of the quad flat pack IC is calculated from the center position of each of the four sides.
a positional deviation calculation means for calculating the amount of positional deviation in the vertical and horizontal directions and the amount of angular deviation in the horizontal plane of the lead, a lead bending inspection means for inspecting the bending of the lead from the variation in the center value of the lead, and the second visual field. A lead float inspection means calculates the vertical variation of the leads of the quad flat pack IC based on the data input from the sensor and inspects for float of the leads; and a test result output means for outputting a lead floating test result.
