Gerber File Viewer

The Gerber File Viewer is a file-based tool that renders Gerber and drill data to help engineers validate board fabrication readiness. It accepts RS-274X Gerber files and Excellon drill data, including ZIP archives, and presents a layer-aware visualization with per-layer visibility and color-coding. Conceptually, the tool treats each Gerber file as a layer that contributes to a composite board image; it then overlays drill hits and copper regions to reveal potential misalignments or missing data. Benefits include faster defect detection, reduced rework, and clearer communication with fabs like JLCPCB. Core features include automatic board outline detection, layer toggles, unit conversion between mm and inches, and exportable outputs for reporting. Use cases range from early design reviews to pre-submission checks before manufacturing orders. The tool differentiates itself through streamlined parsing, robust handling of ZIP archives, and a focus on inspection rather than full CAM functionality. This enables designers to verify layer presence, drill data integrity, and copper geometry without requiring desktop CAM software, delivering immediate value in both professional and educational settings.
