Abstract
The process is for incorporating an inductive circuit in a printed circuit board and consists of providing at least two windows (2, 3) defining a magnetic circuit. The zone between the windows forms the magnetic core (4). The inductive circuit is realised by at least one plastification of all the faces of the core on which a winding (7) is formed by metallic deposition. Notches (5) are provided at the edges of the magnetic core. The circuit arrangement enables a self-induced current to flow through the windings.
