Multilayer board setup to avoid blind and buried vias

igalloway
igalloway over 14 years ago

I have my layer setup as ((1*2)+(15*16))

On a recent board, I found myself with blind vias that I wasn't expecting.

They just occured by themselves when routing from the top layer to a middle layer.

How can I avoid this?

 

Yes - I have read about settingt the via's to the background color.

That seems like a tedious and cumbersome approach to me.. shouldn't there be a DRC to avoid blind/buried vias ? or highlight them?

 

OR at least would there be a CAM that could change all vias to go through the whole board?

 

Thanks,

-iain

    Sounds like you need to get rid of those inner parentheses.  The parens determine what layers can have vias, so your existing setup will allow vias through the whole board as desired, as well as blind vias between 1 and 2 and 15 and 16.
