Shielding for electromagnetic interference

摘要

An electromagnetic shield (11) having at least a portion (10) formed from a composite material comprising liquid crystal polymer filled with an electrically conductive filler, preferably carbon fibre. The shield (11) is a housing with a lid (7) and in use houses at least one radiation emitting component (1 and 5), and said portion (10) comprises at least one wall extending downwardly from the lid (7) dividing the housing into separate areas. The shield reduces crosstalk between components and the composite material provides mechanical advantages over conventional shield materials.
