Making the bottom layer to have a ground plane and ready to send to the PCB manufacturer

Former Member

Hi,

 

I now have my *.brd file completely routed and checked with no error.  I

believe I got some info in the past how to proceed to prepare necessary

gerber files for the PCB manufacturer.

 

But one thing I had not done before is making the bottom layer to have a

ground plane.  Questions: 1) How to do that? 2) Anything to watch out

for when I start generating gerber files with the bottom ground plane?

Any tips to watch out for when generating the necessary gerber files are

appreciated!

 

Thanks!

    Hi,

     

    use a POLYGON in the bottom layer and name it the same as the ground

    signal.  RATSNEST calculated the polygon and shows the copper plane.

    There are some parameters concerning the polyogon you can adjust.

    See HELP POLYGON for more.

    The polygon has no influence on how to generate Gerber data.
