Abstract: A method of certifying uniform distribution of mechanical pressure comprises an apparatus for moving an object, the apparatus including an arm (410) with a joint (430) for adjusting a fixture (420) having a flat surface area (420a). The fixture includes vacuum suction for holding the object. The method further uses a pressure sensor (450) with a flat surface area (450a), displaying output voltage as a function of mechanical pressure applied. When the sensor is placed on a chuck with vacuum suction, the apparatus moves (460) to bring the flat fixture surface in touch with the flat sensor. Mechanical pressure is applied from the fixture to the sensor; the voltage output of the sensor is monitored to certify uniform distribution of the fixture pressure across the sensor area.
