 Bigger Bigger  Smaller Smaller  Reset Reset

Hi all. I'd like to get some PCB's made up as I have never done it before.

I decided to start with something simple, and proven, so I decided to try the Sparkfun WS2801 breakout board from here https://www.sparkfun.com/products/10504

I downloaded the EAGLE files, made a few small changes to the silkscreen and then started to follow the Sparkfun tutorial https://www.sparkfun.com/tutorials/109. I used the job cam file that they link to also http://www.sparkfun.com/tutorial/BeginningEmbedded/9-EaglePCBs/sfe-gerb274x.cam

I exported the files, zipped up the 7 and uploaded to batch PCB. But I get a failed DRC check smiley-sad it mentions traces to small on top copper I think, so I went back to the layout and increased all trace sizes to 0.016 and tried again, but I got the same result?

I thought maybe I had messed something up, so I opened the standard Eagle files from Sparkfun and tried again without making any changes but it still failed the DRC check once I uploaded it?

I'm really stuck now  smiley-eek

I use the .dru checks and .cam files from iteadstudio to make sure my files are manufacturable.

http://imall.iteadstudio.com/open-pcb/pcb-prototyping/im120418001.html?options=cart
Click Download, save the CAM and DRC files in the /cam and /dru folders in eagle.

From the Board editor run Tools:DRU, select the itead .dru file, and check your layout.
Fix things (or accept them) until you're down to just Stopmask errors.
Then run File:Cam processor, that opens a new message box. Select File:job:open job, and select the itead .cam file, and process away.

This makes 13 files, zip those up & send to the board house.

I don't have eagle open in front of me, but these steps are pretty close.

Take the original sparkfun design and put that through the (iteadstudio) DRC check, that will show if you are doing anything wrong, then do your design mods.

On a related note, as Itead and SeedStudio use the same Fab Factory, could the DRC rules from either be used?

First mistake.  Do NOT use BatchPCB.  I am also a member of the sparkfun forums and the forum for BatchPCB is filled with members complaining about the site and the DRC check.  They "upgraded" the site about 8 months ago and it has never been the same.  When they pushed out the new site, it had so many bugs that no one could get boards made for months.  And their still having problems.  It's been 3 months since they did any fixes for the bugs, and they are not going to fix it.  The BatchPCB staff quit posting on the forums also.

These are the recommended fab houses:
http://imall.iteadstudio.com/open-pcb/pcb-prototyping.html  (great boards for less money.  quality is OK)
http://oshpark.com/  (for small boards.  boards get pricey for the large ones, but the quality is unmatched.  Plus free shipping!)
Also with OSH Park, you don't need the Gerber files.  Just upload the brd file.

Attached is how your board would look from OSHPark.  It would cost 2.50 with free shipping.  yea..

PS: I just noticed that Itead is now selling flexible printed boards (FCB).  That's awesome.  I may have to try them.

Thanks guys, I have given up with batchPCB after what I have read on their forum also. Can't believe they are so slow to fix their processing issues.

Have ordered from OSH park instead, looks and sounds promising smiley I have noticed an error by me already, there appears to be silk screen on the resistor pads whoops. I uploaded the .brd file instead of messing around with the gerbers - I wonder if that is why it happened?

Nope, it was on your screen as well.  Cause it was on mine.  You can email him at pcb@laen.org and let him know that you have to make changes.  email the new .brd file and he will change it for you.  He's a good guy.

At the moment in using elecrow.com services.I had used itead services but the are slow ,besides the quality which is very good.So far the manufacturer is very fast and the have very good communication with the customer.I really recommend their services.They also have files to generate the  gerber files and to check the board.

Wow, that was quick my board was added to a panel and its gone already, never mind hopefully they can still make them and I will just scrape off the silk screen when they arrive smiley

elecrow looks good also, but since I've never had boards made before I think I will stick with OSH for my first few.
