Using quality (and expensive) board houses at work, errors still do occur.
Stuff like wrong drill sizes, missed holes, misinterpreted artwork, etc..
I've never had faults from poor materials or inherently bad process,
just human error or machine malfunction.
Of course I ask them to put things right if they mess up, at the
prices they charge I don't feel like accepting sub-standard goods.
They sometimes make a couple extra, and sometimes they call to ask if
it is OK to send less than the ordered amount because not all came out
well. So things do go wrong that the customers (usually) never see
because internal QC catches them.
Electrical faults (like a short or break) I haven't seen even a single
one, so I don't order electrical testing if it costs extra. The boards
are low tech enough so that this is no big risk.
