I'm doing layout on a board(blind/buried) that was previously Class 2 and is
changing to Class 3.
After reviewing Appendix A on pg 25 of IPC-6012A, I've only been able to
identify the annular ring on vias as an issue that would affect me during
the design process. It seems that most of the other charcteristics would
have to upheld during fabrication or assembly of the boards.
Can anyone tell me of any other areas that I would have to watch for during
layout in order to adhere to Class 3 specs?
