Zoom, pan, and measure. Check your design before manufacturing.
A Gerber file is a manufacturing image description, and Gerber review refers to the process of checking whether each exported layer correctly represents the intended board geometry. That definition is important because fabrication errors often start as export or packaging issues rather than schematic or layout mistakes.
| File Type | Main Content | Why Review It | Common Failure Mode |
|---|---|---|---|
| Copper Gerber | Tracks, pads, pours | Verify electrical geometry | Missing shapes or wrong layer polarity |
| Mask Gerber | Solder mask openings | Check pad exposure | Unexpected tenting or exposure |
| Silkscreen Gerber | Reference text and marks | Confirm readability and clearance | Text over pads or clipped markings |
| Drill File | Hole sizes and locations | Validate hole intent | Offset drills or missing tools |
Yes, files are processed locally in your browser. No data is uploaded to any server.
Ensure your files are valid Gerber format (RS-274X). Try uploading as a ZIP archive with all layers included.
Yes, use the measurement tools in the viewer to check dimensions and spacing on your PCB design.
Drill files, fabrication notes, stackup information, BOM data, and pick-and-place outputs all contribute to a complete production package.
Check the rendered layers against the fabrication drawing, board outline, drill chart, and placement intent so the export package matches the released design.
