N2 - Further reduction in the firing energy of SCB/LTNR firing device has long been a bottleneck of micro initiation system in MEMS fuze.Technical approaches for reducing the firing energy of SCB firing device are obtained by testing the firing sensitivity, such as decrease in dimensions, proper aspect ratio, addition of V-notch angle, reduction in particle size of ignition composition, atc. In the experimental process, 3.83 V of the minimum all-firing voltage, 0.073 mJ of firing energy and 229.88 mA of the maximum no-firing current are achieved. Two ignition mechanisms can be found by analyzing firing phenomenon and electrical characteristics curve. One critical ignition mechanism is electrothermal ignition, of which corresponding bridge area of SCB transducer element is 7.65×102 μm2 and the mass is 3.55×10-6 mg. The other is electro-explosive ignition, of which corresponding area is 5.68×102 μm2 and the mass is 2.64×10-6 mg.
