How to know if the design contains buried/blind vias

gussabina

Hello:

 

Is there a way to know (or a Report that shows) the kind of vias the design is using? In other words, I want to be sure there are NOT buried/blind vias in my design.

I finished a design using blind vias but my PCB manufacturer charges between 4 to 6 times the price for PCB with normal vias only. So I'm changing all blind vias to normal, but I want to be sure there aren't any blind vias.

Anyway, it's also easy to get confused when adding a via if the wrong start or end layer is selected.

 

I haven't see a way of knowing buried/blind vias. I would appreciate any help.

 

Thanks

Gus

  • Not sure but wouldn't this be evident in the layer stackup and the drill pairs that are defined?  So if you have drill pairs for top to bottom only then you would have normal through-hole vias.

     

    Also, I think your drill table will show this if you put one on the drill layer.

  • Also you could generate Outputs > NC Drill Files and take a look at *.DRR, this is a text file that will show layer pairs that will be drilled so you should be able to spot any that are not top to bottom.
