Yes. Its common in military work and power control. We either press heat
sink layers between layers or adhere them to one side of the board. The
ones that are pressed within the boards are accessed by removing
dielectric material in certain areas by controlled depth milling usually
on the edges of the board.

Wow, making your own heat sinks!  Are these so special they must be
custom made?  There is nothing on the open market that would do the
job?

Subject: Re: [TN] HEAT SINKS

Just now, I happen to work with heatsinks from Plansee. Their material
is 
little expensive, but what products! The thermal, mechanical and 
environmental properties are outstanding. There is probably nothing
better.

Just a thought.
