It’s always a good idea to review your PCB gerber files before committing them to the PCB fabrication house. We use ViewPlot to check our PCBs, what software to you use and what are the common errors you look for? Leave your comments here, or join the discussion in the forum.
We review the gebers for any problems that might have happened in the export process. It’s not an in-depth check, that happens in the CAD program, this is just a quick verification.
Eagle3D and EagleUp have become an important part of our board pre-flight too. A clear 3D rendering of the PCB instantly highlights silk problems and potential part placement issues.
