We sometimes need to define a thruhole via as a stack up of blind microvias and buried vias. This is becasue on th eTop and Bottom layers I need a smaller pad, that cannot be acieved with thruhole via, but only with blind micorvias. Is it possible in PCB Editor to define such a via, or at least to place a via over another in this way?
I'm an experienced self-taught on Orcad Layout 10.5, and I'm in the process to change to PCB Designer 16.6, and I find it very difficult to mentally 'translate' old Layout commands and names to PCB editor, they are so different!
Thanks in advance,
If I understand your goal then it is easy to achieve. When you create a via padstack using the Pad Designer you can define the pad size for the top layer, the bottom layer, and the internal layers separately.
Not so simple, I want it to be constructed with different drill sizes also, but the PAD Designer only allows one drill for the whole via.
Sorry. I missed that you needed different drill sizes also.
Have you tried Setup->B/B Via Definitions using different seed vias.
HI Craig, thanks, but what do you mean with different seed vias? I want to put all of them in the same place.
