Abstract:
1. An electrical device, comprising: a mounting substrate on which electronic components are mounted, said mounting substrate comprising a multi-layer printed circuit board and having a conductor track structure for electrically interconnecting the electronic components; a boundary track of said conductor track structure on said mounting substrate having a surface and forming a boundary between a region on said mounting substrate to be shielded and a region on said mounting substrate with no shielding, at least one component of the electrical components is in the region to be shielded, the boundary track being connected to a fixed potential, at least one cutout being defined through a surface of said electrical conductor and into said mounting substrate; an electrically conductive shielding element positioned on said mounting substrate for shielding said at least one component against electromagnetic radiation, said shielding element having at least one latching mechanism in engagement with said at least one cutout, said engagement between said at least one mechanism and said at least one cutout connecting said shielding element to the fixed potential; and a filter device integrated into said printed circuit board, said filter device comprising a capacitor having a first conductor area formed by a first track of said conductor track structure and connected to a fixed first electrical potential and a second conductor area formed by a second track of said conductor track structure and connected to a second electric potential, said first and second conductor areas arranged in different layers of said multi-layer printed circuit board and opposing one another in said printed circuit board.
