A multilayer printed circuit having a control circuit including n vias that are connected in series between a first and a second electrical terminal so that an applied electric current passes at least partially through each one of the n vias. The control circuit includes track portions in each one of the layers, each one of the n vias connecting a track portion of one layer to a track portion of another layer. The control circuit includes a measurement device for measuring a potential difference across its terminals, storage for storing a threshold value and a comparator for comparing the potential difference with the threshold value so as to validate the printed circuit when the potential difference is lower than the threshold value.

Method and circuit for controlling quality of metallization of a multilayer printed circuit board

An angular position sensor for sensing the angular position of a rotor rotating on an axis relative to a stator, including a ferromagnetic target, of substantially ovoid cross section, rotating together with one from among the rotor or the stator, and a sensitive element including a first set of coils that are angularly evenly distributed, rotating together with the other from among the rotor or the stator, the coils being axially arranged in line with the target in order to be able to measure a distance from the target so as to deduce therefrom an angular position of the rotor relative to the stator.
