About Power Plane in double layers

[arm_learner]

Hi All,

Is it placing two ground copper pour in 2 layers PCB?

Thanks

If you have to layout a double layer PCB,

1. Two Sides Copper Pour are Ground Plane.

2. Power and Ground Plane for each side copper pour.

Which one is the best?

Thanks

What voltages are you working at ?

If high voltage, make the top ground because if anybody touches it they will not be at rick of getting an electric shock.

Use the space you have for GND pour. Low impedance ist most important for GND, as it is the reference for the signals. For the supply voltages use thick traces and bypass caps.

Got it~~ Thz

Ur board is 2 layers and because this,it can't be used in very high freq. If ur board need to run in high freq, try other type, eg. 4 layers .There is no good solution for 2 layers.
