Changing the board size on an existing layout

Rico Suave

 Hi,

 

I am new to this community. I have a question in regards to what the easiest way would be if you take and existing layout ( 6-layers, components placed, traces routed, planes established) and have to make the board smaller than its original design. I created the new card outline, but what about the existing design, Route Keepin and planes. Is there a better way than to ripup the whole design and start over?

 

Thanks,

Rico

    Depending on how much smaller the board is, will dictate how drastic the changes may be.  If it is a lot smaller, then obviously components may have to move along with associated etch. If not so much, then you might be able to move some components and then reconnect.  There are a lot of unknown variables, so this is just a high level suggestion.

    As for the planes and route keepin, I find it easier to delete and recreate using Z-Copy with the contract option (assuming your planes are not split).  You could also just edit the shapes manually.
