Patent ID: 7015711

Claim:
Apparatus for the testing of circuit boards, comprising: a mounting area for holding a circuit board to be tested; test fingers for serially contacting of circuit board test points of a circuit board to be tested with contact tips, wherein the test fingers are capable of being moved along the surface of a circuit board to be tested by a movement device and being lowered so that the contact tips contact the circuit board; an optical detection device for the optical detection of at least one of the contact tips of the test fingers, optical detection device moving with the contact tip at least in a direction along the surface of the circuit board to be tested; an analysis unit to record an image of the at least one contact tip and to determine the distance of the contact tip from the center of a circuit board test point to be contacted, and a control unit to control the movement of the contact tip on the basis of the distance of the contact tip from the circuit board test point to be tested, as determined by the analysis unit.
