印制电路板及其制造方法和终端技术

一种印制电路板及其制造方法和终端，通过印制电路板的地平面(10)与指南针电路的地平面(11)隔离，两个地平面单点连接(13)，可有效阻断印刷电路板上地回流经过指南针电路的地平面(11)，降低印刷电路板上地回流所产生的磁场对电子指南针(12)的干扰，提升电子指南针(12)的精度。

Printed circuit board and its manufacturing methods and terminals

A printed circuit board and its manufacturing method and terminal. By isolating the flat surface (10) of the printed circuit board and the horizontal plane (11) of the compass circuit and two ground plane single point connections (13), the surface of the printed circuit board can be effectively blocked by the horizontal surface (11) of the compass circuit, and the magnetic field produced by the backflow of the printed circuit board is reduced. The interference of the electronic compass (12) enhances the accuracy of the electronic compass (12).
