Abstract:
A test fixture adapted for alignment of test probes with test sites on a printed circuit board under test to translate test signals from the test sites to external test electronics comprising:a stationary probe place having a plurality of holes extending therethrough;an array of receptacleless probes having contoured tips extending through the holes in the probe plate and individually movable in an axial direction through the probe plate;a top plate for moveably supporting the printed circuit board under test generally parallel to the probe plate so that the test probes can contact the test sites;the top plate having contoured guide holes for preventing the test probes from walking out of the probe plate; andan interface located below the probe plate and in contact with the test probes to translate the test signals to the external test electronics when the board under test and the probe plate are moved toward each other.
