Another Project Update – Headphone Tub Amp

So I received my PCB’s in the mail a week or two ago now.  They were wrong. Within the CAD drawing the actual dimensions of the board were incorrect. If you reference the picture below you will see that there are gray holes in the 4 corners. Those symbolize no copper through holes for mounting. Well the way the Eagle CAD file is setup, the PCB fabricator see that as the outside edge of the board. So the traces stop in alignment with those dimensions, as well as the actual board itself get clipped. This is no good. Results in missing Ground and 12v traces, as well as a few components don’t make it onto the board.

Here’s were things get really good though. I was going to live with this problem and just eat the 20 bucks. I emailed OSH Park just looking for help with my CAD file. Not only did Laen at OSH fix my CAD file, rather quickly, but he refunded my money, apologized and said my next boards would be on them. You don’t find many places anymore that give service like that. I can’t recommend OSH Park for PCB work more. What a great company!!

So presently I’ve resubmitted the corrected CAD files and there already at the fabricators.
