Step 3: so that electrode plug passes the housing with the electric cap of opening, in order to the electrical fuze igniter is assembled in the housing of electric cap, wherein provide energy by power supply or electric capacity to the film resistance of electrical fuze igniter, it is enough burnt hot and point of amorce is heated to design temperature so that film resistance produces, thereby light point of amorce, and then ignite electric cap.
11. a method of making electric detonator is characterized in that,
Step 1: SMD film resistance is provided and it is welded on the pad of electric detonator circuit control panel one end;
Step 2: point of amorce is provided and it is wrapped up in to be attached on the SMD film resistance to form the electrical fuze igniter; And
Step 3: so that the other end of electric detonator circuit control panel is electrically connected with the wire of electric detonator electrode plug, and so that the electric detonator circuit control panel that is electrically connected and electric detonator electrode plug pass the housing with the electric detonator of opening, in order to the electrical fuze igniter is assembled in the housing of electric detonator, wherein by the film resistance discharge of electric detonator circuit control panel control capacitance to the electrical fuze igniter, it is enough burnt hot and point of amorce is heated to design temperature so that film resistance produces, thereby light point of amorce, and then ignite electric detonator.
