Abstract
The invention relates to a method of manufacturing a magnetic power component and to a magnetic power component. The component comprises a multi-layer coil (1) which consists of several windings disposed in the layers, first and second electrical conductors (5, 6) which are electrically connected to the selected windings, and a first and a second core part (7, 8) which are arranged to direct magnetism to the windings. The first side (2) of the multi-layer coil (1) is provided with a cavity (9) and the first core part (7) is at least partially mounted in the cavity.
Claims9
A method of manufacturing a magnetic power component, the method comprising the steps of
- manufacturing a multi-layer coil which comprises several windings disposed in the layers,
- electrically connecting first electrical conductors and second electrical conductors to the selected windings, and
- mounting a first core part on the first side of the multi-layer coil and a second core part on the second side of the multi-layer coil,
- wherein the first core part and the second core part being arranged to direct magnetism to the windings,
- removing material from the first side of the multi-layer coil to provide a cavity, and
- mounting the first core part at least partially in the cavity to allow placing of the magnetic power component on a circuit board so that the first side of the multi-layer coil is against the circuit board and the first core part in the cavity is at a distance from the circuit board and that the first electrical conductors and the second electrical conductors can be connected to the conductors of the circuit board.
