What gerber viewer do you use and why?

Posted on Friday, November 18th, 2011 in utilities by DP

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.

  • Missing solder pads – problems with the footprint, the solder pad is sometime buried by mask
  • Drill problems – drills outside board or flipped
  • Silk problems – CAM didn’t export expected silkscreen layers

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.

    The FOSS gerbv is what I’ve used for a while. When I was at SparkFun’s BatchPCB, they used gerbv’s libraries to render gerber files on the site. A couple of years ago, I wrote up a to use gerbv to look at and even edit a gerber file.

    I’ve been using Viewmate from PentaLogix for close to 8 years now. It is free and pretty easy to use.

  3. kiran says:

    I used KiCAD to open gerber files. For my next PCB I will use KiCAD for designing also.

  4. David says:

    Even though I use KiCAD for creating my layouts I prefer using GEDA’s Gerbv to check the gerbers. Works quite nicely.

    At work we use PentaLogix ViewMate which is a free download (but not open). That’s not to say it’s necessarily the best, if you want to edit your gerber (which should probably never be done) you have to buy an upgraded tool. I only just became aware of the free/open gerber viewers; the one that comes in KiCad seems capable.

  6. Sjaak says:

    I just use an online viewer to check the gerbers. I use it mainly for spotting silkscreen errors.

  7. Shaos says:

    I’m using gerbv for a few years already (at least since 2005)
    Last version even has an ability to remove something from gerbers ;)

    GerberLogix. : Free for non-commercial use

    Viewmate or CAM 350 for me.

  10. rsdio says:

    What about a free .CAD file viewer? Assembly shops usually want a .CAD file, which Eagle can produce using gencad.ulp, but I’ve had a few problems and would like to double-check the files before sending them out.

    Please try mine:, if you have real 3D graphics hardware.

    What an epic video!

    Probably it’s not really the good place for this question related to Gerber.
    But the thread is active again… Let me hope an answer!

    I’ve already asked this question somewhere, but I didn’t receive any operational answer (just the one like “Google is your friend…”)

    I’ve an HPGL plotter good enough to plot PCB. I’ve already used it in the past with PCB (outdated now) tools and the result was good enough.

    Eagle doesn’t enable a HPGL output.

    However I’m quite sure that someone, somewhere has written a good Gerber to HPGL translator.
    At least for basic PCB this may be fine for prototyping.

    Does somebody have successfully tried a such converter? Wich one?

    thank you

    Hi Marc, sorry I haven’t tried it, but I have a suggestion, you could stat a new topic in the forum, under general discussions, it should stay active (in the face of people) for longer then this post, someone might turn up that did try it out.

    I started with Numerical Innovations free Gerber Viewer – DFM Now! and then found out they had a full CAM tool that does everything I need. The pro version is called FAB 3000 Professional. This helped me out alot!

  16. Jony says:

    Hi, CAM350 is mainly used by the factories and therefore for me the safest in order to display the 100% accurately. I like Viemate too. But better not use GerbV, I think it is not accurate.

    Be aware of Viewmate on the Pentalogix website. You first have to register by giving an awful lot of personal details, next you get a link to a “broken” ftp directory. Looks more like a scam to collect email addresses and personal data ?!?!
