    摘要: An electromagnetic baffle arrangement includes a lid (22) having a trough or air gap (30) in the side walls of each cavity (23) of lid (22). Conductive strips (28) are applied to a layer of printed circuit board (26) and each of the legs (31) of lid (22). Optionally, to eliminate circulation of electromagnetic signals within air gap (30) a grounded bolt (32) may be inserted aperiodically.
