Abstract

The invention relates to the field of printed circuits, in particular to a method and a system for reducing circuit absorption or emission power of a printed circuit board, which comprises the following steps of: scanning the circuit board to obtain a data image and the size of each element; parameters of high-frequency elements on the circuit board are optimized, and a low-power circuit board is manufactured; measuring the electromagnetic radiation field intensity distribution condition of the low-power circuit board to obtain a strong interference area; and a shielding layer is added at the strong interference area. According to the mode, the emission frequency of the elements on the circuit board can be reduced firstly, so that the electromagnetic interference on the adjacent elements can be reduced firstly, then areas with strong interference can be found by measuring the electromagnetic distribution condition on the improved circuit board, and then shielding layers can be installed in the areas respectively. And the anti-electromagnetic interference capability is further improved.

Description

technical field [0001] The invention relates to the field of printed circuits, in particular to a method and system for reducing the absorbed or transmitted power of a printed circuit board circuit. Background technique [0002] With the development of electronic science and technology, the electromagnetic environment of various electronic devices has become more and more harsh, and printed circuit board circuits are more and more susceptible to interference from the external electromagnetic environment. This requires improving the anti-interference of the printed circuit board circuit. [0003] The existing circuit board has poor anti-interference performance, which reduces the stability of the circuit board in use. Contents of the invention [0004] The object of the present invention is to provide a method and system for reducing the absorbed or transmitted power of a printed circuit board, aiming at improving the anti-interference ability of the circuit board and maki...
