Jeff,
Lithographic substrates (e.g. printed wiring boards) built with organics have common electrical and mechanical properties when compared to ceramics, glass, sapphire, etc.  They are obviously fabricated much differently also.
It has always seemed to me to be a distinction ahead of its time.
My guess is that IPC was mimicking the DSCC-DLA distinction between FSC 5998 and 5962, which happened well before my  time.

FYI here is a link to some "new" stuff that bridges the two from a company spawned from my alma mater:

I have been ask the question, "To what does the 'Organic' in the title "Sectional Design Standard for Rigid Organic Printed Boards' refer?"  I thought that this was a reference to the polymers used, but had to admit that I was un sure. So I ask my learned colleagues, what does the organic in the title of  this specification refer to?

Thanks in advance for the clarification.
