Hi all,
Can anybody pls tell, What is the effect of Unbalanced Layer stack up ? or sometimes it is required to unbalance the Core or prepage thickness for some Desing requirements?
And what is the difference if We use Core in center or we use Prepage in center .because somedody told me that we shuld use like
Top Layer
CORE
Signal 1
Prepage
Signal 2
CORE
Bottom layer
it there any difference if we replace core and Prepage ?
Thanks in Advance
