PCB板布线,其实是一项系统性较强的工作,并且有多方面的综合性比较强的要求,不光是PCB的布线美观,结构紧凑,最为关键的一点还是信号的抗干扰处理。在高频信号多的情况下,容易产生很多的电容耦合;在工作模块多的情况下,容易产生电感耦合;并且如果有很多地分块的话,还要考虑共模干扰,以及串 PCB board wiring, in fact, is a systematic and strong work, and there are many aspects of the more comprehensive requirements, not only beautiful PCB layout, compact structure, the most crucial point is the anti-jamming signal processing. In the case of many high-frequency signals, a large number of capacitive couplings tend to occur; in the case of many working modules, inductive coupling easily occurs; and if there are many sub-blocks, common mode interference,
