ABSTRACT:
A device for testing a printed circuit board (PCB) (30) wherein the connection between the PCB to be tested and the testing circuits of the device is ensured by conductive needles guided by at least one perforated guiding plate (34). The PCB to be tested comprises at least one standard pattern included in a predetermined set of standard patterns of closely spaced contact regions. An intermediate plate (20) has a first surface, turned towards the PCB to be tested, comprising a first pattern of pads arranged according to the standard pattern, and a second surface comprising a second pattern of pads regularly arranged according to a pitch compatible with that of the needles, each pad of the first surface being electrically connected to a pad of the second surface.
