PCB Review
Design review report for a radar sensor board
A full review of a radar sensor board before fabrication: power and reset sequencing, communication buses and signal return paths, with every finding ordered by severity and the action to take for each one.
The problem
The client had a radar sensor board designed and wanted it checked before ordering boards. They needed to know what could fail, how serious each issue was, and what to change.
What I did
- Reviewed the schematic and the PCB layout, block by block.
- Checked power and reset sequencing, so the radar does not start before its supplies are stable.
- Checked the communication buses, pull-up resistors and power-good signals.
- Checked the layout for signal return paths, for example fast QSPI and SPI lines crossing gaps in the ground plane.
- Wrote a report with a findings summary, a severity for each finding and a detailed section with the current design, my assessment and the required action, using screenshots of the schematic and layout.
The result
A 26-page review report the client could act on, with the findings classified by severity and status, and a more robust board they can order with confidence. Client and application details are kept private under NDA.
