如何让抄板设计更高质量,欣荣电路板抄板公司根据多年的PCB抄板设计经验,总结出以下规则,可供广大客户参考!

1.ZUJIANBUZHI

组件布置合理是设计出优质的PCB图滚球体育的基本前提。关于组件布置的要求主要有安装、受力、受热、信号、美观六方面的要求。

1.4.XINHAO

信号的干扰PCB设计滚球体育中所要考虑的最重要的因素。几个最基本的方面是:弱信号电路与强信号电路分开甚至隔离;交流部分与直流部分分开;高频部分与低频部分分开;注意信号线的走向;地线的布置;适当的屏蔽、滤波等措施。这些都是大量的论着反复强调过的,这里不再重复。

2.2.DIXIANBUZHI

欣荣PCB抄板公司的经验是,为了提高系统的可靠性(而不只是做出一个实验样机),对地线无论怎样强调都不为过,尤其是在微弱信号处理中。为此,必须不遗余力地贯彻"大面积铺地"的原则。

狗急跳墙的着数:实在滕不出地方而又不甘心庞大的地线被区区一根信号线拦腰切断时,就让这个信号委屈一点,走跨接线吧。有时,欣荣电路板抄板改板设计不甘心仅仅拉一根光秃秃的导线,这个信号恰好又要经过一个电阻或其它"长脚"的器件,欣荣抄板设计就可以名正言顺的延长这个器件的管脚,使之兼任跨接线的职务,既通过了信号,又避免了跨接线这个不体面的称呼:-(当然,在大多数情况下,我总可以让这样的信号从合适的地方通过而避免与地线的交叉,唯一需要的是观察力和想象力。
