Exploding foil initiator

Abstract

An exploding foil initiator assembly is provided comprising a first layer of dielectric material, a second layer of dielectric material, a third layer of dielectric material, and a flyer. The first layer of dielectric material comprises a first pair of vias. The second layer of dielectric material comprises a first surface adjacent to the first layer of dielectric material, a second surface opposed to the first surface, a second pair of vias, and a bridge. Each of the second pair of vias extends from the first surface to the second surface and is in contact with one of the first pair of vias. The bridge is positioned on the second surface and is electrically connected to the second pair of vias. The third layer of dielectric material is positioned on the second surface of the second layer and comprises a bore positioned at least partially over the bridge forming a barrel. The flyer is positioned in the barrel on the bridge.
