GerbView

GerbView is a software tool designed to view and inspect Gerber files and related manufacturing data used in printed circuit board (PCB) production. It provides a graphical representation of each fabrication layer, enabling designers, engineers, and fabrication houses to verify artwork before fabrication.

The program supports common PCB data sets, including RS-274X Gerber files, Excellon drill files, and NC drill data. Users can switch between layers, adjust transparency, measure dimensions, inspect aperture definitions, and annotate issues. It often includes features such as color-coded layer display, zoom and pan, and the ability to export reports or printouts.

In manufacturing workflows, GerbView serves as a verification and communication tool, enabling quality checks, design reviews, and preparation of manufacturing data for CAM systems. By providing an independent view of copper, soldermask, silkscreen, drills, and vias, it helps detect misalignments, missing layers, or out-of-tolerance features before boards are fabricated. Note that GerbView is typically a viewer and does not modify source files; any annotations or redlines are designed for review and must be reconciled with the original design data.

Origin and availability timelines vary by vendor, but GerbView-type tools are commonly distributed as standalone applications or as components of broader PCB design suites. They are typically supported on multiple operating systems and complemented by scripting or automation options to streamline review tasks.
