Abstract
A chip slapper is presented, having a substrate, a conductive layer disposed above the substrate face, and an intermediate layer disposed between the substrate face and the conductive layer. The conductive layer and intermediate layer form a first land and a second land atop the substrate face, with a bridge formed of the intermediate layer spanning between the first land and the second land. A first adhesion portion is attached to the first land, and a second adhesion portion is attached to the second land, wherein at least a portion of the bridge is not overlaid by the first adhesion portion or the second adhesion portion.
Claims29
A chip slapper, comprising:
- a substrate comprising a back and a face substantially opposite the back;
- a conductive layer disposed above the substrate face;
- an intermediate layer disposed between the substrate face and the conductive layer;
- a first land comprising the intermediate layer, and the conductive layer, a first edge adjacent to a first region of the substrate that is covered by neither the intermediate layer nor the conductive layer, and a second edge adjacent to a second region of the substrate that is covered by neither the intermediate layer nor the conductive layer;
- a second land comprising the intermediate layer and the conductive layer, a first edge adjacent to the first region of substrate, and a second edge adjacent to the second region of substrate;
- a bridge disposed between the first land and the second land comprising the intermediate layer and omitting the conductive layer, a first edge adjacent to the first region of substrate, and a second edge adjacent to the second region of substrate;
- a first adhesion portion disposed over the first land and spanning between the first region of substrate and the second region of substrate;
- and
- a second adhesion portion disposed over the second land spanning between the first region of substrate and the second region of substrate,
- wherein at least a portion of the bridge spanning the first edge and the second edge is not overlaid by the first adhesion portion or the second adhesion portion.
