Since I was speaking of wonderfully designed boards I recently came accross
a warpage problem on a eight layer board that caused problems.
I was wondering if anyone here would have any suggestions in case it comes
up again.
---------------- Cu 1
~~~~~~~~~~~~~~~~ 7628
~~~~~~~~~~~~~~~~ 7628
---------------- .008 core 2/3
~~~~~~~~~~~~~~~~ 1080
~~~~~~~~~~~~~~~~ 1080
---------------- .008 core 4/5
~~~~~~~~~~~~~~~~ 1080
~~~~~~~~~~~~~~~~ 1080
---------------- .008 core 6/7
~~~~~~~~~~~~~~~~ 1080
~~~~~~~~~~~~~~~~ 1080
---------------- Cu 8
with the 7628 layer being required for controlled impedence work.
This ties into my previous post about designers having open minds.
