[PCB_FORUM] Re: backplane

Paul,

I've done it.

The 2.20 spec has the route example for you.
The min layer count we came up, to make the signal integrity guy happy
was 22.

Let me know if you want more info.

I have a backplane with 20 slots. There are 2 fabric slots and 18 other slots. We want a full mesh topology. Each slot has to have a connection to every other slot. The connecter I'm using has 4 pairs in each row. All 4 pairs of one row on a slot go to 4 pairs on another slot. I've been asked to try and figure the least amount of layers this requires. No matter what I try, the layer count is extremely high. Does anyone know of anyplace on the web that might show some routing strategies for this? Have any of you ever done anything like this? Any help would be greatly appreciated. Thanks.
