Online Gerber Viewer

The Online Gerber Viewer accepts RS-274X Gerber files and Excellon drill data to generate a unified board view for inspection and validation. It targets PCB designers, contract manufacturers, QA engineers, and CAM technicians who must verify layer contents, board outline, drill layouts, and inter-layer alignment before fabrication. By surfacing missing apertures, misalignments, and dimensional discrepancies early, it reduces rework and accelerates supplier handoffs. The tool emphasizes deterministic parsing and structured diagnostics for automation.

Conceptually, the workflow parses each file, normalizes coordinates, assigns a stacking order to layers, and computes a board bounding box. It then renders a multi-layer view with distinct color coding per layer and exports metadata such as width, height, and per-layer counts. This enables cross-system validation and archival.

Unique value lies in its combination of strict data validation, multi-layer consolidation, and machine-readable outputs that fit into QA gates and CAM pipelines. It supports quick validation during data exchange, enables traceable revisions, and reduces the risk of fabrication errors in both prototyping and production runs. Typical use cases include single-board prototypes and multi-board production handoffs where timing and accuracy are critical.
