layer stackup in dru file?

autodeskguest

hello all

 

I am totally confused on how to set up layers in the DRU file for a board

with mixed via's. The board I will be doing is an 8 layer board with thru

via's layer 1-8, blind via's layer 1-2, and buried via's layers 2-3. I am

able to get thru via's with blind or thru via's with buried. But I can't

seem to get all three specified at the same time. Any help would be greatly

appreciated.

 

Thanks

  • Hi Jim,

     

    I've got the same problem with a 4 layer board!

    Did you ever get to the bottom of it (so to speak!)?
