Abstract
A thin film bridge initiator for initiation of explosives includes a thin film resistive element of a selected composition of Nichrome, alternately Tantalum Nitride either of which is evaporated upon (in the case of Nichrome) or sputtered upon (in the case of Tantalum Nitride) an alumina substrate. A prime explosive mix is contained against the initiator film elements by a positive retention contactor assembly.
