I’ll complete the PCB now: first I’ll size the board and stackup, then add the mounting holes, place the components by function, and finally set the high-current layout rules and review the result.

Placement is done and organized by power flow. I’m setting the high-current PCB rules next, then I’ll route the board and clean up the remaining PCB checks.

The first routing pass finished, but it left a few stray copper segments. I’m removing the bad trace stubs now, then I’ll rerun routing once for cleanup.

I completed the schematic, board sizing, mounting holes, placement, and two routing passes, but I’m blocked from finishing cleanly because the remaining PCB issues are stubborn floating/dangling trace fragments plus a couple unrouted connections that the available autorouter did not resolve after cleanup. The board is close, but it is not yet at a zero-issue manufacturing state.

What I finished: compact 100mm x 80mm 4-layer board, corner mounting holes, functional placement, and wide-power routing preferences. What remains: a small set of routing cleanup items on the PCB, so the next step is targeted manual routing cleanup or a revised routing strategy before export.
