<p>A screening arrangement for screening an electronic circuit (26) from electromagnetic interference comprises a chassis (21) and a lid (23) with dividing walls forming four mutually screened compartments (25, 29-31). A multilayer circuit board (32) carrying interconnections (65, 67) and ground planes (61-63) extends through the dividing walls into all of the compartments and connects to the electronic circuit (26) in the first compartment (25) and a connector (38) in the fourth compartment (31). The circuit board (32) carries interference filters (36) in the second compartment (29) and voltage limiters (37) in the third compartment (30). <IMAGE></p> |
