Abstract
A process for producing capacitors having thinner electrodes on dielectric substrates for use in multilayer ceramic capacitors which use less precious metal ink and produce thinner capacitors. Basically, the process begins with coating a support with a mixture of a finely divided ceramic material and a resin to form a green ceramic dielectric substrate of substantially uniform thickness but with a necessarily rough surface. A coating of resin is applied over the green ceramic to form a substantially smooth surface. A desired pattern in an ink comprising precious metal particles in a resin is formed, such as by silk screening, on the coated ceramic to form the electrode. Because of the smooth resin surface and finer metal particles, the ink coating may be relatively thin. The composite may then be fired to produce a capacitor suitable for use in monolithic multilayer capacitors.
