Abstract
A method of positioning probe tips relative to pads includes: focusing on each of the probe tips in a first image as viewed by a microscope and collecting the coordinates of the corresponding probe tip relative to a first reference point in the first image; focusing on each of the pads in a second image as viewed by the microscope and collecting the coordinates of the corresponding pad relative to a second reference point in the second image, a relative position of the second reference point to the first reference point being predetermined; matching the pads with the probe tips when the quantity of the probe tips and the pads are equal while minimizing a maximum value of the distances calculated between each of the probe tips and the corresponding pad; and moving the probe tips to touch the pads with the maximum value minimized.
