I'm designing a simple 6 layer board with following as core components.

http://www.ti.com/lit/ds/symlink/tm4c123gh6pm.pdf http://www.ti.com/lit/ds/symlink/afe4403.pdf

I using this stackup enter image description here

Now I'm looking at the drill pairs so that will give optimal performance by not bumping the cost. I heard that buried via will incur more costs compared to blind or thru hole via.

Please recommend some multilayered board drill pair for simple typical 6 layer board.

Thanks

  • What's your question? – 12Lappie Feb 13 '17 at 14:09
  • drill pair recommendations to reduce PCB cost? – Dee Feb 13 '17 at 14:10

    Talk to your board house. The answer depends on their exact process. – Olin Lathrop Feb 13 '17 at 14:12
  • Yes I did talk to them what they suggested is to use thru hole or buried vias instead of micro and blind. – Dee Feb 13 '17 at 14:13
  • But my question is what are the commonly used drill pairs defined for such typical 6 layer boards. – Dee Feb 13 '17 at 14:15

    So long as you use thru vias, this has nothing to do with cost, which makes it hard to respond to your premise. – Scott Seidman Feb 13 '17 at 14:38
  • Lets say If I use 3 drill pairs (Top-Bot, Top-Sig1, Sig2-Bot), then extending/ending the VIAs with nets (ex, Power or clock signals) to Top/Bot/GND/VCC/Sig1/Sig2 layers regardless where they start and end, will be a good practice? – Dee Feb 13 '17 at 15:02

  • @12Lapointep Thank you very much. Think the link you shared has more or less answered my question. I will need to check couple of things regarding 0.5mm BGA before making my mind. – Dee Feb 13 '17 at 15:34
  • Guys, thanks for all the help could you please tell me how to mark this question as answered? – Dee Feb 16 '17 at 12:26
