Abstract
A method of testing circuit boards, in particular non-componented circuit boards in which the level of the surface of a circuit board to be tested is detected automatically in a contacting process, and the further contacting operations are then controlled on the basis of the level detected. By this process, the control of the movement of the test probes of the finger tester effects automatic matching to the level, which is of particular advantage in the testing of flexible circuit boards, since their surface may have a three-dimensional form.
