Internal cermet routing for complex feedthroughs
One aspect relates to a composite, including a ceramic body having a first layer surface and a second layer surface and at least one cermet conductor that electrically connects the surfaces. The composite includes a first layer with the first layer surface, a first ceramic, a first hole and a first cermet element in the first hole, a second layer with the second layer surface, a second ceramic, a second hole and a second cermet element in the second hole, and an intermediate layer that is located between the first and the second layer. The intermediate layer includes an intermediate layer ceramic, an intermediate hole and one intermediate cermet element in the intermediate hole. A projection of the cross-section of the first hole and a projection of the cross section of the second hole onto a plane Px,y are arranged offset to each other.
