Problems solved by technology

[0004] The resistance alloy layer on the chip alloy foil igniter is relatively narrow, which will lead to insufficient contact surface. If faced with insensitive agents, the narrow resistance alloy layer has insufficient ignition ability, which will easily lead to detonation failure.

Abstract

The invention provides an ignition resistor capable of enhancing firepower, the resistor includes a substrate, a resistance layer and a metal combustion-supporting layer, the resistance layer is located above the substrate, the resistance layer is connected to electrodes, and the metal combustion-supporting layer Located above the resistance layer and directly in contact with the resistance layer, the metal combustion-supporting layer is a non-conductive combustion-supporting material, and generates heat through the resistance layer to ignite the metal combustion-supporting layer. The invention enhances the ignition ability, reduces the rejection rate and avoids misfiring.

Description

technical field [0001] The invention relates to the technical field of electronic blasting, in particular to an ignition resistor capable of enhancing firepower and a manufacturing method. Background technique [0002] Unless specifically indicated otherwise, what is described in this section is not prior art to the present application and is not admitted to be prior art by inclusion in this section. [0003] The bridge wire igniter is the ignition method that has been commonly used by people. The radial stretching effect of the bridge wire can easily lead to deformation of the bridge wire, resulting in a change in the resistance of the bridge wire, which affects the ignition performance of the igniter, and may cause the bridge wire to break and cause the igniter to misfire. Therefore, people have developed a sheet-type alloy foil igniter. This igniter generally processes the alloy onto the substrate through a specific process, and forms a narrow alloy layer as an ignition ...
