ABSTRACT OF THE DISCLOSURE The present invention relates to devices for the quality control of the electrical insulation of printed circuits made in particular in multiple layers superposed on insulating supports of laminar structure by mean conventional or hybrid technologies. To this end, the control device according to the invention essentially comprises : - a specific sensor circuit constituted by a supple insulating screen comprising a plurality of conduc- ting studs; - a scanning circuit associated with said sensor circuit constituted by a metallized insulating layer having at least two coplanar conducting zones insu- lated by at least one transverse electrical disconti- nuity; - a measuring apparatus indicative of the galvanic insulation existing between two contiguous conducting zones of said scanning circuit.
