Stackup & Board Layout

Thinking of using:

6 Layer Board: SIG - GND - PWR - SIG - GND - SIG

Advantages of this stackup:

  • Each Signal layer has an adjacent ground plane

  • Split power plane for high current handling & power distribution

  • Extra signal layer - can route using stripline connections

Other Board Considerations:

  • Weight of copper (1oz vs 2oz) - I’m thinking 1oz should be fine, especially given a dedicated power plane for higher current handling

  • Most likely to be a double-sided board

  • FETS + Power on outer signal layer closest to PWR

  • MCU + Gate Driver on other

  • Mounting pattern + board dimensions?

    • COTS module is 70mm x 30mm
