Abstract
An electronics card comprising a stack of printed circuit layers, each comprising an electrically insulating support having at least one conductive track extending thereon, and two electromagnetic shields extending respectively over a top face and over a bottom face of the stack, each shield comprising a grid and a plate that are superposed and electrically conductive, each extending over an electrically insulating support, and the conductive tracks being obtained by solid copper type etching. The invention also provides a device including such a card, and a method of protecting such a card of such a device against a lightning strike and against electromagnetic radiation.
