Nice one, qu1ck is now in my buddies list.
qu1ck:
Well this is a hilarious fuckup (images clickable):
Do you see it?
How about now?
And yes, I double checked my gerber files, they are obviously correct :D
I'll try to scrape the solder mask off, maybe this batch is salvageable still.
How did they even manage to do this? Well, back to the fab with ya.
bitseeker:
Wow, not just one pad, but two of them. Maybe a bug in their software? Both cases were similar in that the trace to the pad continued straight through. However, there's a trace on the lower left that went through the pad to a via and that didn't get solder masked. Odd.

Yes, it will be not pretty but it should work.
