PCB Placement Redesign

Execute the bottom/power PCB placement redesign now. Set board to 32 mm x 32 mm rounded-square with 8 mm corner radius and Standard 4 Layer stackup overrides: L1 Signal, L2 Ground Plane, L3 Power Plane, L4 Signal. Do not route. Preserve schematic components; do not delete. Ensure bottom-board components are included for PCB/BOM and top-board-only components are marked Exclude from PCB/BOM/Pick&Place. Place J7 exactly at X=+5.0 mm, Y=-17.6 mm, rotation 0°. Place U1/J2/RT1/U2/Q1/F1/J1/D1/PS1/L4/D2/D3/IC1/K1/J5/J6/D9/M1-M4/Q2-Q5/D4-D7 and local passives in the required functional groups. Run DRC/fit/routing feasibility checks, do not route, and update/create the project file 'Bottom Power PCB Placement Notes'. Keep final concise.

I’ll apply the bottom/power PCB placement redesign, keep the schematic intact, exclude top-board-only parts from fabrication outputs, then run placement/fit/DRC feasibility checks without routing.

I found the existing project files list and am applying the requested board geometry/stackup first, then I’ll use the project notes to classify bottom vs top-board-only parts.

The board setup operation is hitting a platform-side “missing project document context” error, so I’m checking whether layout/document state is accessible before retrying with a lower-level edit path.

Processing was stopped.
Here's a summary of what I was working on:
Troubleshooting tool issues
It looks like the tool is failing, which has me wondering if there's an active run. I might need to inspect the project metadata or check if the current project isn't in the right context. I see that the layout appears to be empty, which is odd. Perhaps there’s no layout document in context. I should report this, but maybe I can still proceed with mutating the layout component positions. It’s worth a try to read the docs for more insight.

Bottom Power PCB Placement Notes
Requested architecture
  • Bottom/power-actuator PCB for the two-board stacked smartwatch architecture.
  • Required outline: 32 mm x 32 mm rounded square, approximately 8 mm corner radius.
  • Required stackup: 4 layers, L1 Top signal, L2 GND plane, L3 power plane, L4 Bottom signal.
  • Do not route during this phase.
  • Preserve full schematic intent; top-board-only parts should be excluded from PCB/BOM rather than deleted.
Shared coordinate / J7 mating datum
  • Top-board mating coordinate for J7: X = +5.0 mm, Y = -17.6 mm, rotation = 0 degrees in the shared coordinate system.
  • Orientation caveat: if the mating connector orientation requires mirroring between stacked boards, keep the same XY datum and verify rotation/mirroring mechanically before routing or fabrication.
Intended bottom-board placement plan
  • J7: fixed at (+5.0, -17.6), rotation 0 degrees.
  • Battery block: J2 on a side edge with U1 nPM1300, RT1 NTC, U2 DW01A, Q1 FS8205A, and F1 close by.
  • USB/charge block: J1 on a side edge with D1 and fuse/protection close; reserve gasket/plug keepout clearance.
  • Stimulation block: PS1 TPS61041, L4, D2, D3, IC1 TLC555, K1, J5, and local passives tightly grouped, isolated from low-voltage logic/J7 for the 10 V stimulation domain.
  • Haptics block: M1-M4 in four corners with Q2-Q5 and D4-D7 near the corresponding motors.
  • User I/O: J6 on the right-side edge; D9 visible near a side/edge.
Current status / blocker
  • Existing layout inspection shows this clone still contains a top-board-focused 40 mm x 40 mm placement, with J7 already at (+5.0, -17.6) but many top-board components placed.
  • Placement mutations were not applied in this session because the layout mutation tools returned: No project document context available / missing project document context.
  • No routing was started.
Required next execution once edit context is restored
  1. Resize board to 32 mm x 32 mm with 8 mm corner radius and the specified 4-layer stackup.
  2. Mark top-board-only components Exclude from PCB/BOM/Pick&Place; clear those exclusions on bottom-board power/actuator components.
  3. Place bottom-board components only, maintaining J7 at the shared mating coordinate.
  4. Run checks for missing footprints, outside-board bodies, body overlaps, density, airwires, and routing feasibility without routing.
