Title: IGNITOR FOR ELECTRONIC DETONATOR
Abstract:
An ignitor for an electronic detonator, the ignitor including a microcontroller and a capacitor mounted on a printed circuit board (PCB) and electrically connected to one another, the microcontroller configured to discharge the capacitor in response to an actuation signal received by the microcontroller, a pair of conductive traces extending from the capacitor, a resistive element extending between the conductive traces and configured to radiate heat in response to current flowing therethrough, and a shroud disposed over the resistive element, the shroud containing a pyrotechnic composition that at least partially covers the resistive element.
