What is the type of PCB.  Is it a BGA of some sort?  Integrating Cu heat
sinks inside or attaching on back side of PCB is a known technology.
Depending on the PCB, whether a BGA or bare board I can assist you better.
Please provide additional information.

Subject:        [TN] Copper Heat Sink

HI there,

I was wondering if it is possible to get a copper slug (or solid villed
via's
etc) manufactured into a PCB.. This is to help dissipate the heat away
efficiently from a very hot component.. You might be thinking why don't I
just use solder filled via's.. well this is because copper is a MUCH better
conductor of heat than solder.
 Has any one done this sort of thing before, or have any other good
ideas.

Thanks in advance,
