The pick-and-place device comprises: 60 (a) a positive pressure chamber forming from a pick-and-place holder (10), a force measuring membrane (20) and a cover (60), wherein a positive pressure is supplied to the positive pressure chamber (60) via a pressure supply inlet (80) provided on the pick- and-place holder (10), and 80 ,.. 72 thus the force measuring membrane (20) is being preloaded; (b) a vacuum chamber forming from 70 the pick-and-place holder (10), the force measuring membrane (20) and a pick-up membrane (40), wherein a negative pressure is provided via a vacuum supply inlet (70) provided on the f tiffs 20 pick-and-place holder (10), wherein the pick-and-place device provides a pressure difference between the work- piece (90) and the pick—and-place device (100), enabling a pick-and-place capability. The present invention also relates to a method of simulating a pressure contact with a work-piece (90) which has force measuring capability and could be used by feedback control to the force a desired range in order to damage on the system set within prevent components or apply a regulated force during contact.
