Plated through-hole ignitor for detonation cord or shock tube

摘要

In a system for igniting detonation cord or shock tube, a plated through-hole in printed circuit board is coupled to a circuit to have high voltage and high current applied to the plated through-hole. The end of the detonation cord or shock tube is passed through the plated through-hole and formed into a knot to secure the detonation cord or shock tube in the plated through-hole. The voltage and current applied to the plated through-hole are of sufficient magnitude to explode the plated through-hole and ignite the detonation cord or shock tube.
