The object of the invention is to provide a machine for the control of printed circuits, of the type comprising a board bearing (1) a plurality of conductive needles that are connectable on their reverse side to analysis means of the electric parameters between one and the other needle, characterized in that: are used two needle boards, one opposite to the other (1, 1') and between them is positioned for the analysis the respective printed circuit card (2); and, one board is made movable respect to the other; the needles are axially movable.

L'invention concerne un dispositif de contrôle de circuits imprimés, comprenant une plaquette (1) qui porte une pluralité d'aiguilles conductrices pouvant être reliées sur leur partie arrière à un système d'analyse des paramètres électriques entre deux aiguilles. Ce dispositif présente les caractéristiques suivantes: on utilise deux plaquettes à aiguilles, l'une opposée à l'autre (1, 1'), entre lesquelles on positionne la carte à circuit imprimé que l'on veut contrôler; on peut déplacer une plaquette par rapport à l'autre; et on peut déplacer les aiguilles axialement.
