Method for exciting conductive material to ignite by inputting and outputting electronic from side of circuit board

Abstract

The invention relates to a conductive material igniting method by inputting and outputting a electronic excitation from a side of a circuit board. The device involved in the method is composed of a PCB printed circuit board, a first bonding pad electrode, a first circuit, a first metallization half hole, an insulation region, a second bonding pad electrode, a second metallization half hole, a second circuit, a discharge region, a first discharge end, a second discharge end and a conductive material. According to the method, an external integrated controller is used for carrying out communication power supply on the electronic excitation detonator. The power is converted into a communication signal and a supply voltage through an input circuit and an energy storage capacitor is charged. After the communication of the integrated controller and the electronic excitation detonator is finished, a detonation command is sent out, a single-chip microcomputer sends an opening signal to the a discharging switch. The discharge switch outputs the capacitance energy to the side surface of the input / output electronic excitation conductive material ignition device of the circuit board through thecircuit board. A conductive material is coated on the first discharge end, the second discharge end and the discharge region, so that the electric conduction material can generate energy capable of generating fast electronic movement and the flame can be emitted. The flame ignites the basic explosive and detonates detonator, and replaces an ignition bridge wire and a firing powder head in the electric detonator and the electronic detonator.

technical field [0001] The invention relates to a method for firing conductive material by inputting and outputting electrons on the side of a circuit board replacing traditional electric detonators and electronic detonator bridge wire firing powder heads. Background technique [0002] The ignition of the traditional electric heating bridge wire is the ignition device of the electric detonator and the electronic detonator, and the ignition powder is the ignition device for igniting the detonator. The performance of the ignition device directly affects the performance of the blasting system. At present, the more commonly used ignition devices include bridge wire pyrotechnics, film bridge pyrotechnics, semiconductor bridge pyrotechnics, metal film bridge pyrotechnics, explosive film bridge pyrotechnics, etc. The mode of action of bridge wire electric fire heating and pyrotechnic agent is mainly the mechanism of heat conduction.

AI Technical Summary

Problems solved by technology

[0004] 1. The production is unsafe: the ignition powder is composed of gunpowder, which is flammable, easy to catch fire due to collision and friction, the production process of the powder should have high precautionary measures, and the raw materials are flammable and explosive, whether manual or automatic. There is a high risk of head assembly

[0005] 2. Insufficient precision: Both the thermal effect of the bridge wire and the ignition energy of the powder head have a time difference in the heating and burning process. Due to the difference in time delay, it cannot meet the requirements of high-precision and safe ignition energy, and the bridge wire or powder head cannot be automatically pasted. Installed on the chip of the electronic detonator

[0007] 4. Complicated processing: the bridge wire does not have welding melting power, and the strong pressure contact makes the process complicated, easy to oxidize, poor contact, and the bridge wire is easy to break

The electronic ignition device replaces the ignition powder head, which solves the problems that the ignition powder head is not resistant to high temperature, flammable, easy to catch fire due to friction and impact, does not ignite when it is damp, and there are risks in the process of manufacturing, installation and use.
