Abstract

In a method for automated determination of the relative position (x/y/z) between a first hole (27) on a first microsystem component (11), which is preferably provided with a first channel (44) opening in the first hole (27), and at least one second hole (29) on a second microsystem component (12), which is preferably provided with a second channel (45) opening in the second hole (29), the two microsystem components (11, 12) lie in a liquid medium (41) at least in the region (25, 26) of the holes (27, 29). Under the supervision of a control device (15) controlled by a computer (22), the first and second microsystem components (11, 12) are displaced relative to one another into different relative positions (x/y/z). Electrical signals (37) are delivered to one of the two microsystem components (12, 12) and are recorded on the other of the two microsystem components (11, 12) as measurement values (38) which depend on the relative position of the two microsystem components (11, 12) with respect to one another. For different relative positions (x/y/z) between the two microsystem components (11, 12), measurement values (38) are determined, from which the relative position (xn/yn/zn) in wh…
