I'm glad you're sharing this, Paul. It gives us appreciation for
their real failure rate vs imagined.<br>
<br>
So, if my tally is right that's one failure for you, one for me, and
either one or two for Chip.<br>
<br>
I've gotten 19 different board designs fab'd by them. If we got OSH
Park design and fab-error totals from others on this list we could
develop a probability. It seems like it might be higher than we'd
like by an order of magnitude or three.<br>
<br>
What did you use for a routing grid size and trace width for this
board?<br>
<br>
I guess it's time to start talking about pogo-pads and 'scope loops.

soldered it all up and ran my test code on the processor and
everything worked fine. I then went to attach it via RS485
and no-go. I finally tracked it down to the eight pads of
the dual-RJ11 socket not being plated through properly. So,
traces that connected on the bottom pads worked fine, but
the few on the top did not connect. I opened a support
ticket with OSH Park and sent them some photos. They looked
at the Gerber files and agreed that the issue was with the
fabrication and not the design. They redid the boards on a
”hot” lot and I had new boards in a week.<o:p></o:p></span></p>
