Thus, the components are directly connected to the chip on the same surface, which reduces the number of through holes in the printed circuit board, reduces the area occupied by the components on the printed circuit board, and simplifies the processing of the printed circuit board.
Or the electronic detonator control chip and the energy storage capacitor are respectively arranged on different surfaces of the printed circuit board. Because the height of the two energy storage capacitors is far larger than that of other elements, the length of the printed circuit board is shortened under a certain width of the circuit board.
Or the two energy storage capacitors are positioned on the same surface of the printed circuit board, so that the thickness of the whole assembly is reduced, and the assembly is more suitable for being placed into an electronic detonator shell.
