How long does it typically take to receive the email telling you if your design passed. I know the FAQ’s says 5 min, but I’ve been waiting a couple hours
Hopefully you got yours back by now 
Usually mine are a few minutes to 20 minutes
Yes, if your pcb design has not passed the drc within 2 hrs, something has have gone wrong. If so, re-submit the design. If you have further questions on whether or not your design needs to be passed or anything else. Email us at Support@batchpcb.com
