Abstract: A printed circuit board (PCB) testing system for testing various types of PCBs includes a base plate corresponding to a target PCB; a plurality of probe assemblies, each having a probe pin electrically contactable with the target PCB and a removably securing member for removably attaching the probe pin on the base plate; a test point selection unit for determining a plurality of test points located on a target PCB to generate a test point selection signal representing the determined test points; and a probe arranging unit, in response to the test point selection signal, for moving and arranging said probes on positions of the base plate corresponding to said each determined test point to thereby bring each probe pin into contact with a corresponding test point.
