Φ Gerber review.
Drop a Gerber/ODB++ zip. We read the layer manifest, drill counts, and aperture headers, then a senior-engineer review flags missing layers, drill sanity, and format issues — cited. Your files never leave your browser except as short text excerpts.
How Φ Gerber works
The tool unzips your package in the browser (nothing is uploaded wholesale), classifies each file by extension and naming into layer types, counts drill hits, and reads short header/aperture excerpts. That manifest plus the excerpts go to the review model, which reasons like a senior EE doing an incoming-package check.
What it catches
- Missing layers — no soldermask, no drill file, no board outline.
- Drill-count sanity against apparent board complexity.
- Aperture/format hints — very small trace/space, mixed RS-274X/274D, missing aperture defs.
- Units/format-header issues, assembly readiness (paste/mask present).
What it can’t do (yet)
It does not render the copper, so it can’t measure real clearances, annular rings, or sliver geometry — that needs a server-side Gerber rasteriser (tracespace / gerber-parser), the documented next step. For a true geometric DRC and a sign-off, that’s PhyVerify.
