[SI-LIST] Re: Designing PCB Stackups

Cody,

Things have been changing considerably due to the fact that most people 
nowadays use high-speed SerDes
links on their boards.  And certainly the situation may vary dependent 
on which corner of the
world you are doing business in.  My understanding is that if 
high-frequency performance matters to you,
the choice of available laminates may and will vary from fabricator to 
fabricator...
