초록

An exploding thin film bridge fracturing fragment detonator comprises a base layer with a bridge layer vapor deposited, e.g., sputtered, thereon. The bridge layer is comprised of an electrically conductive material and includes a bridge portion which interconnects significantly larger portions of this layer. An inorganic insulating layer of rigid fracturing material is vapor deposited, e.g. sputtered, on the bridge layer. A flyer layer is vapor deposited on the insulating layer, whereby the flyer layer is insulated electrically and/or thermally from the ...
