Hi Yuan,
This increase is possible only if the thickness increase substantially
reduces the warpage of the PBGA or substantially decouples the influence of
the die on the global expansion mismatch. It still sounds too large, though.
To say something more, I need the full details of your analysis and some of
the result details.
