Subject: HDI PCB - micro-via
Steve,
I have never inspected any HDI PCBs before and was asked to perform inspection to them in accordance to IPC-A-600 and if necessary IPC-6012. I have no idea what I am looking for as I stare at those pictures which I randomly took from two of the cross-section buttons. I flipped through the whole IPC-A-600 and 6012 but not able to see any images/pictures that correspond to what I see. Also am I suppose to use 6012 or 6016 to assist in the inspection criteria? I am totally lost.
Kindly post the pictures to TechNet so that some kind souls can help me out of this dark tunnel. J
Thanks and regards,
~wee mei~
