Among the many online services for PCB manufacturing, I was impressed by the SeeedStudio‘s offering: they aggregate many orders to offer professional service at a very competitive price.
I tried out the service ordering 10 PCBs, maximum size 5x5cm, with a price of 9.90$ + 3.52$ for shipping (to Italy) – less then 10 euro. SeeedStudio doesn’t accept Eagle .brd files, so I thought to write this short guide with some hints to use Fusion PCB at its best.
Download from Fusion PCB webpage, two archives:
- DRU for 2-layer board
- Seeed Gerber Generater 2-layer board
Unzip the first one in dru subfolder of the main Eagle installation folder, the second in cam subfolder.
Open your Eagle project and focus on Board layout: to test PCB compliance to Fusion PCB rules, click on Drc button in the right toolbar, then click on Load… and choose the file Fusion_eagle_rule_v1.1.dru:
Click on Check, if everything is ok, DRC Errors window won’t show any errors; otherwise you have to modify your PCB following the error messages.
To export the project, from File menu click on CAM Processor.
In CAM Processor window, click on File -> Open -> Job… and choose the Seeed_Gerber_Generater_v0r95_DrillAlign.cam file:
Click on Process Job: Eagle will write some new files in our project’s folder.
Before sending those files to SeeedStudio, I strongly suggest to check their content with a Gerber editor/viewer: in my experience sometimes I found errors in the exported files (for example if you use proportional fonts, they may change size).
A great opensource software is Gerbv, which has been ported also on Windows platforms.
To open your project, click on File -> Open layer(s)…
Choose (pressing CTRL key, you can select more than a file at the same time) the 7 files you have to send to SeeedStudio:
- .GTL (top layer)
- .GBL (bottom layer)
- .GTS (solder stop mask top)
- .GBS (solder stop mask bottom)
- .GTO (silk top)
- .GBO (silk bottom)
- .TXT (drill sizes and positions)
Hiding/Showing each layer you can check if export was successful:
If everything looks good, prepare an archive with the files listed above.
Connect to SeeedStudio website, in the page where you can order the FusionPCB service.
Upload your ZIP file:
and complete your order choosing PCB quantity and parameters; you can follow the order status in the customer area of Seeed’s website.
After some weeks, here are the PCBs…
