We designed a board with about a 1" square bare (exposed) copper (both sides) to
help dissipate heat near a specific component.  The board was OSP already.
Could not have been too effective though, we ended up needing to attach a
heatsink anyway.

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,
