No, brand new design and revision for a customer of ours. We have had nothing but issues with the manufacturer like this and have seen really odd things happen during reflow.
We have received so many with edge damage like this that I had to ask if this is normal and I am being anal or is this a problem with the supplier. The sad part is that the customer is designing around this device so we will be stuck with this kind of quality unless I really push and drag my feet right now. I need some unbiased opinions on the issues. Some issues get to the point that you almost have to prove that your not whining and this isn't right. I am forwarding all responses to them for further evaluation.
