Problems solved by technology
[0002] At present, the existing ignition modules generally include a housing, which is provided with a cavity, and an ignition control circuit and a circuit board are installed in the cavity, which has the problems of inconvenient installation and layout of electronic devices and poor heat dissipation of power resistors, and the long-term Over time, there is a problem of loosening the circuit board; there is a terminal block on the housing, and the terminal base and the housing are fixedly connected by screws. However, the ignition module of this structure is easy to rust and fall off when the ignition module is used for a long time , so that the positioning of the wiring seat is not reliable, the ignition module cannot be used normally, and long-term use leads to poor thermal conductivity, unstable performance, and low temperature resistance

Embodiment Construction
[0017] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, a specific implementation of the present invention will be described below in conjunction with the accompanying drawings.
[0018] Such as figure 1 and figure 2 As shown, it includes a module circuit board, a high-power IGBT tube 10, a housing 5, a solderable pad 9 with welding leads and a high-power resistor (not shown in the figure), the module circuit board is a ceramic circuit board 1, and the ceramic circuit board The high-power resistor is pre-embedded in 1, and two high-power IGBT tubes 10 are symmetrically arranged on the surface of the ceramic circuit board 1. The ceramic circuit board 1 is provided with a main control circuit, and the housing 5 is provided with a positioning piece 4. The ceramic circuit board 1 Placed in the shell 5 next to the positioning piece 4, two enameled wires with different wire diameters are wound on the...

The invention provides an automotive ignition module with resistors pre-buried in a ceramic board. The automotive ignition module comprises a module circuit board, high-power IGBTs, a shell and high-power resistors, wherein the module circuit board is the ceramic board; the high-power resistors are pre-buried in the ceramic circuit board; the high-power IGBTs are arranged on the surface of the ceramic circuit board; a control circuit is arranged on the ceramic circuit board; a locating sheet is arranged in the shell; the ceramic circuit board is close to the locating sheet and placed in the shell. The automotive ignition module has the beneficial effects that the conventional heat dissipation mode based on a heat dissipation sheet is abandoned, so that the space of the ignition module is saved; furthermore, the size of the whole board is reduced, and the cost is reduced.
