AbstractA thin film bridge initiator is mounted on a header for use in a detonator where a primer is activated by heat from the thin film. The initiator includes a substrate which carries a pair of metallic beam-type leads connected by a thin film bridge which activates the adjacent primer. The beam-type leads are affixed (welded) to a pair of electrical pins which are on adjacent sides of a slot in the header. The entire structure is very cost effective, reliable and provides fast functioning and safety. In addition, a process of manufacturing several bridge initiators at one time on a single wafer is provided.
