Gerber Viewer

Gerber Viewer is a small, yet effective application that serves to visualize Gerber and Drill files, with the possibility to print such content on demand.
For those unfamiliar with the term, Gerber refers to a type of image typically used in the printed circuit board industry that previews the PCB with details such as drill holes, masks, layers and legend.
Gerber files can only be viewed using dedicated applications, one of which is Gerber Viewer. It’s free of cost, easy to use and appropriate for the average computer user.
It’s wrapped inside a portable package, which means you can carry it on a removable drive and launched on any computer without touching the system’s registry.
As far as appearance is concerned, Gerber Viewer sports basic looks which makes the application more accessible. However, there is such a thing as too simple and the program may very well fall under this category, considering its rudimentary interface.
Files can be added using the dedicated menu using a custom scale and printed on the spot. Moreover, the layers detected inside the image can be deleted individually from the built-in layer management dialog.
There’s not much else to say about Gerber Viewer, except for the fact that it needs a considerable amount of enhancements. One of them is related to the user interface, which could use a complete makeover, followed closely by aspects of functionality, such as zoom or pan functions, as well as export options.
On the other hand, the utility hasn’t received updates in a while, therefore future releases are less probable.
