Back in 2005 I got one of the FE-5680A rubidiums. The one I got came on 
the full original circuit board. I thought I would make up a PDF to show 
what the original board looked like and the kind of heat sink they 
mounted it on.

The board is large and has about 140 sq in of almost solid ground plane 
on both the top and bottom.

The PDF that I created is here...
