Abstract:
An apparatus for testing a printed circuit board comprising:a probe having needle portions provided on both ends and a flange on the exterior circumference thereof, wherein at least one of the needle portions of the probe is movable;an interface board being parallel to the printed circuit board and having patterns of conductivity; andprobe retention means having a pass-through aperture larger than the diameter of the probe and shorter than the diameter of the flange so that the probe vertically passes therein, the probe retention means being disposed between the printed circuit board and the interface board, wherein the probe retention means is parallel to the interface board and fixed to the interface board such that the probe retention means and the interface board are spaced apart therebetween,wherein the flange is disposed between the interface board and the probe retention means to define the probe's travel such that the probe does not fall out from the probe retention means and wherein the probe is slidably retained in the pass-through aperture of the probe retention means when force is applied to the probe,wherein one of the needle portions of the probe comes in contact with the printed circuit board and the other needle portion of the probe comes in contact with the conductivity patterns of the interface board when the printed circuit board is tested.
