What most of you do with the above cert. of conformance that comes on a certain batch of PCB's from the PCB manufacturers ? It also comes with a micro section of a PCB showing the internal of a PTH Via Barrels. I kept receiving them from every PCB Product that we have (during every delivery) but I dunno what to do with them and I'm not from QA department. Is QA suppose to have them ?
Thanks in advance.
Good resource for new beginners.
