Barbara,
Is it always necessary that you specify the core and prepreg thickness on
your drawing?  The standard you call out may not be what your vendor stocks.
Also the prepreg thickness as presses will be different from different PWB
fabricators depending on their type of press and parameters they use.  I
wondered where you went since you left HLS.
