Fab. gurus -

I am trying to decipher the stack-up of a board design provide by one of my suppliers for a 4-layer RF board we are having built.  The call out for material is FR406 0.010 CM S1/S1 18X24, I believe that this designates an Isola FR406 core 10mil thick with class C/M tolerance and 1oz copper both sides in an  18"x24". Is this correct? If so I may have an answer as to why the RF function is different than a previous build using 1/0 cores.


Thanks in advance for your help,
