Abstract

Apparatus for producing multilayer varistors using ceramic ink and electrode ink consists of a succession of stations, in which alternating layers of ceramic ink and electrode ink are laid down on a substrate. The stations may be printing stations in which either a ceramic ink screen or an electrode ink screen is used to apply the appropriate ink to the substrate. In a first printing step, a layer of ceramic ink is laid down, within a region determined by a mask area of a ceramic ink screen. In the following step, electrode ink is laid down in regions determined by mask areas of the electrode ink screen. The apparatus includes transfer mechanisms for advancing substrates from station to station for successive printing operations, and control mechanisms for regulating and coordinating the successive printing operations and substrate travel.
