I work for a CEM. We are having some quality issues with some pcb's that came from China. (I know, big surprise) Can anyone with pcb manufacturing experience look at some pictures I have and give me an opinion as to what could go wrong in the pcb manufacturing process that would cause these "defects" I put defects in quotation marks because our China supplier is trying to tell us these boards meet IPC-A-600 standards. They say it is strictly cosmetic and will not effect the board functionally. Any & all help will be greatly appreciated.
