Abstract:
1. Method of testing non-componented printed circuit boards using a finger tester with several fingers which are automatically traversed to contact circuit board test points of a circuit board to be tested, in which each of the test fingers has a test probe provided with a contacting sensor, which is used to determine when a probe tip of the test probe comes into contact with the surface of the circuit board to be tested so that, with the aid of this point in time and the position of the probe tip at this point in time, the level of the surface of the circuit board to be tested is determined, the level being a height of the surface of the circuit board in a direction that is perpendicular to the plane of the circuit board, and contacting processes for contacting further circuit board test points may be controlled on the basis of the determined level.
