The invention relates to a three-dimensional electronic system for a steering engine based on rigid-flex printed boards. The three-dimensional electronic system comprises four layers of printed boards which are stacked from top to bottom, the top printed board bears and installs a telemetering control unit of a steering engine, the middle printed board bears and installs a low-power unit of the steering engine, the secondary middle printed board bears and installs a power driving unit of the steering engine, and the bottom printed board bears and installs a power supply unit; the top layer printed board and the middle layer printed board are connected through a first interlayer flexible printed board; the top layer printed board and the secondary middle layer printed board are connected through a second interlayer flexible printed board; and the secondary middle-layer printed board is connected with the bottom-layer printed board through a third interlayer flexible printed board. According to the three-dimensional electronic system, the rigid-flex printed board structure is adopted to replace internal cable connection, and through the three-dimensional layout after the flexible printed board is bent, the structure is more compact, the space proportion is small, and the manufacturability is more optimized.

    本发明涉及一种基于刚挠印制板的舵机用立体化电子系统,包括自上而下层叠布局的四层印制板;顶层印制板承载和安装舵机的遥测控制单元,中层印制板承载和安装舵机的低功率单元,次中层印制板承载和安装舵机的功率驱动单元,底层印制板承载和安装供电单元;顶层印制板与中层印制板之间通过第一层间挠性印制板连接;顶层印制板与次中层印制板之间通过第二层间挠性印制板连接;次中层印制板与底层印制板之间通过第三层间挠性印制板连接。本发明的立体化电子系统采用刚挠印制板结构代替了内部电缆连接,通过挠性印制板折弯后的立体化布局,使得结构更加紧凑,空间占比小,工艺性更加优化。
