Additional layers, more copper, added vias (to tie layers together),
external heatsink (attached by screws or thermally conductive
material/adhesive),  internal metal core ($$$).  However, you did not state
what kind of cooling you had in mind:  conductive, convection, or
convection w/forced air cooling?  Some forms of heat dissipation work
better than others, depending on the application.

Hi All:

I am just wondering if anybody know how to improve heat dissipation on a
PCB.  That would include additional layers, more copper...

Any help is greatly appreciated

Thanks
