An integrated barrel/bridge detonator subassembly includes a polyimide flyer layer, a conducting layer, and a barrel layer. The conducting layer has an electrically conducting material laminated to a first side of the flyer layer. The conducting layer consists of a single layer of an electrically conducting material. The electrically conducting material forms a first land having a first connecting pad, a second land having a second connecting pad disposed opposite the first land, and a bridge disposed between and providing electrical conductivity between the first land and the second land. A barrel layer formed of an insulative material is laminated to a second side of the flyer layer substantially opposite the first side. The barrel layer has an opening disposed substantially opposite the bridge.
