新建四层板时候会定义地层和电源层，默认是覆铜的，不需要进行覆铜操作。可以在内电层分割里面分割内电层。
Title: Re: Using guard traces for return current instead of ground plane Post by: c64 on September 22, 2021, 06:23:41 am Actually, even if you have ground plane on the bottom layer, is it a good idea to have guard traces on the top level as well? They are much close...
我的理解是在当内电层与焊盘连接的relief connect，即辐条状连接，被你的polygon cutout 侵占时就会提示有starved thermal。当然前提是你启用了Design rule checker 中split plane drc report option的report starved thermal选项 参考资料：http://wiki.altium.com/display/ADOH/Internal+Power+and+Split+...
if we make ill-considered cuts in the ground plane (possibly with the intention of “conveniently” routing some other trace), the return currents of the power converter stage will get diverted along the sides of any intervening cuts, and will thereby effectively createslot antennason the PCB....

pcb地平面的分割 the split ground plane PCB地平面的分割 经纬 魏丽丽王力 (西安电子科技大学机电工程学院,陕西西安710071) 摘要 一个完整的地平面能减少电路板的EMI和串扰问题.在数模混合布板时,数字电路的同步开关噪声往往会 影响敏感的模拟电路。分割的地平面能够提供高的噪声隔离度,但同时也会引起另外的一些EMI...
Power Plane Domain Splitting Having a single well of power for all the components on a signal layer to draw from makes a lot of sense if they all have the same voltage requirements. Increasingly, however, more complex high-density PCB designs have made the practice of splitting a power ...

PCB中plane和layer有什么区别 plane是所有Layer的其中一个,Layer是指层,例如有常见的信号层Signal] Layer为正面,在这一层,画一根线就是画一条导线,即凡是走线的地方就表示有铜皮连接。 云汉007 2019-05-26 09:00:00 Ground-truth数据面临哪些挑战? Ground-truth在自动驾驶汽车产业具有很高的的附加值,它涉及...
