Copper pouring,which is a PCB Design Considerations

2016/8/9 13:45:37

There is a two layer board with no ground or VCC plains as I can't go through the grief process. My question is should I use a copper pour? Currently I have three possibilities which I am contemplating. Implement a copper pour connected to nothing Do not use a copper pour Implement a copper pour connected to ground

No pour is better than a floating pour for signal integrity reasons. When you have a floating pour you are increasing the coupling capacitance between signals so you are increasing the chance of cross talk. In general the pour that is grounded will perform the best, but you should be aware of image current flow.

If you're etching it yourself, you should add copper pour connected to nothing. If you're having it etched by a PCB fab, then leave the board without a pour.
