Abstract
A printed circuit board includes metallization layers are stacked along a vertical direction and separated mechanically from one another by electrically insulating layers. A coil extends along a vertical winding axis and has turns formed by conductive tracks made in respective metallization layers, the turns being electrically connected to one another by pads going through at least one of the electrically insulating layers. A superimposition, in a plane parallel to the metallization layers, of the conductive tracks of the coil, made in a first metallization layer and a second metallization layer, that are immediately consecutive in the vertical direction, forms a pattern having two axial symmetries relative to X and Y axes orthogonal to each other and parallel to the metallization layers. The conductive tracks of each of the superimposed metallization layers are devoid, of themselves, of axial symmetry relative to the X or Y axes.
