Electromagnetic shielding screen and circuit supporting substrate fitted out with such a screen

摘要

A device shielding a circuit located over a substrate includes a band formed from side faces of the device for encompassing the circuit. A top surface of the shielding device is removably located over the band. The side faces are inclined to allow stacking of another shielding device on the band of the original shielding device after removal of the top surface while maintaining shielding of the circuit.
