Importing Altium PCB Project Issues

flux

Updated M.2 SDR 4RCV Layout Symmetry Checklist.
Added:
  • A dedicated stackup and controlled-impedance section
  • Explicit 4-layer target
  • Copper-weight targets for outer and inner layers
  • Dielectric target ranges for L1-L2, L2-L3, and L3-L4
  • Controlled-impedance guidance for 50 ohm RX lanes and 100 ohm differential nets
  • Notes on keeping all four RX lanes on equivalent layers/geometries
  • A fabrication record table for final solved widths, gaps, copper, dielectric, and via policy
If you want, I can next tighten this further into a specific 4-layer fabrication proposal with first-pass trace-width placeholders.

Add that to the project spec as a PCB stackup section with 4 layers, 1 oz outer copper, 0.5 oz inner copper, 100Ω differential and 50Ω single-ended targets.

Added to Project Specification.
Included:
  • 4-layer PCB stackup
  • 1 oz outer copper
  • 0.5 oz inner copper
  • 100 Ω differential target
  • 50 Ω single-ended target
  • notes to solve final widths/gaps from the fabricator stackup and keep matched RX routes layer-consistent
If you want, I can also add a recommended layer role table next, like L1 signal, L2 ground, L3 power/signal, L4 signal.
