The invention is intended to provide a sputtering device in which a single sputtering chamber is equipped with a plurality of supports and a target-positioning mechanism for rotating the supports to position the targets into film-forming position. The apparatus may include a housing component and a mass damper coupled to the housing component by a first elastic member and a second elastic member. One of the spray head’s axes of rotation is coaxial with the lance. The conference call is set up in a conferencing bridge and the phone of the subscriber is routed to the conferencing bridge.
