Abstract:
A printed circuit includes a hole, a stack, one or more first coils, a magnetic core, and a pad. The hole passes through the vertically through the board to receive a conducting wire. The stack comprises metallization layers vertically stacked and separated mechanically from one another by electrically insulating layers. The first coils fulfill functions of a measurement coil and of an excitation coil. Each first coil has turns wound solely around the magnetic core. The magnetic core forms a first magnetic ring surrounding the hole and extending horizontally between metallization layers. Each turn of each first coil is formed by two conducting tracks produced, respectively, in metallization layers situated above and below the first magnetic ring. The pad passes through an insulating layer and passes through an interior of the magnetic ring, electrically linking the two conducting tracks.
