GND on two layers

autodeskguest

LS,

 

Is there a thumbs rule connecting two layers.

 

On the bottom and on the top layer I have a GND polygon.

To reduce stray current I would like to connect these two using via's.

 

Regards

  • Oh yeah, if you are thinking that knowing the voltage drop is important,

    it may not be. If you plan on using that ground plane as a voltage

    reference you should just run parallel ground traces that don't carry

    current to anyplace that needs to know ground voltage (like an opamp

    input or voltage regulator). These are separate from the plane returning

    current to ground potential and generating voltage drops.
