Bill,
Every fabricator will have their own mix of 'standard' stocked materials and
thus will likely have their own internal 'standard' for a build when none is
specified in the fabrication details but from shop to shop there is no
standard.

Subject: [DC] Standard construction for a 4 layer board...
I need to ask the designers and particularly the manufacturers a
question.
IS there a standard construction for a 4 layer FR4 board?
What thickness core and what prepreg arrangement would be used if I
asked for a IPC 4101/26 material to be used without specifying the
stackup thicknesses?
Best regards,
