An ignitor resistor generates heat to ignite explosive material.In a digital electronic detonator, the ignitor resistor converts the electrical energy into heat energy to generate ignition. Its working principle is that the remote control charges the internal capacitor of the electronic control module, then the order of ignition is issued, and the capacitor is discharged through the ignitor. When compared to a traditional bridge wire, the ignitor resistor can accurately control the ignition time of the detonator. The ignitor resistor is the most critical factor that determines whether the entire digital electronic detonator can be successfully ignited.
Features
- Using alumina ceramic substrate, the mechanical strength is far better than FR5 substrate. When the resistor is subjected to mechanical shock, external stress and reflow soldering, it will not damage the active area.
- Add a heat insulating layer on the substrate. In ”All Fire”, the heat generated by the current is enough to ignite the pyrotechnic material, will not be dissipated by the ceramic substrate in such a short time (down to 0.1ms); in ”No Fire”, the heat will dissipate through the ceramic substrate out in long duration such as 10s. It not only guarantees rapid ignition in ”All Fire”, but also guarantees safety in ”No Fire”.
