# pcb-mechanical-reliability This skill checks early PCB mechanical reliability for robot-dog virtual prototypes. It consumes board geometry and mounting metadata, then writes deterministic fit, clearance, stiffness, and connector-risk reports. ## When To Use Use this skill for: - PCB stiffness, flex, mounting hole, and standoff checks. - Connector clearance, cable bend radius, and strain relief checks. - Board-to-enclosure fit risk before CAD/PCB iteration goes deeper. - Producing `pcb_fit.json`, `pcb_reliability_report.json`, and `connector_clearance.json` for `robot-dog-digital-twin` gates. ## Workflow 1. Read `<project>/pcb_mechanical.yaml`. 2. Check board dimensions, thickness, edge clearance, and enclosure clearance. 3. Check mounting holes and standoff spacing. 4. Estimate board flex from unsupported span and vibration load. 5. Check connector clearance, nearest support, cable bend radius, and strain relief. 6. Write reports into `<project>/reports/`. ## Commands ```bash python skills/pcb-mechanical-reliability/scripts/check_pcb_fit.py skills/pcb-mechanical-reliability/examples/quadruped_mvp python skills/pcb-mechanical-reliability/scripts/write_report.py skills/pcb-mechanical-reliability/examples/quadruped_mvp ``` ## Rules - Keep MVP checks deterministic and conservative. - Treat enclosure clearance below 2 mm as a blocker. - Treat excessive board flex, insufficient standoffs, or unsupported power connectors as blockers. - Do not run FEA or import CAD/PCB
