Embodiment Construction
[0021] combine Figure 1-3 The low ignition voltage semiconductor bridge miniature ignition assembly includes three parts: semiconductor bridge transducer chip (1), asymmetric miniature ceramic electrode plug (2) and electrothermal sensitive ignition powder (9). Fix the rectangular semiconductor bridge transducer chip (1) in the trapezoidal groove (3) of the asymmetrical ceramic electrode plug (2) with an adhesive (8), adopt ultrasonic welding, and use bonding wires (6, 7) Connect the two metal pads on the semiconductor bridge transducer chip (1) to the two-leg electrodes (4, 5) of the ceramic electrode plug (2) respectively, so that the two leg electrodes of the electrode plug ( 4, 5) and the two metal pads of the semiconductor bridge transducer element to form a circuit path, and the semiconductor bridge transducer element is filled with electrothermal sensitive pyrotechnic powder (9) refine the neutral trinitroresorcinol lead to form an ignition component .
