Thanks Derek, the method you describes works great for parts where you
have access to the heat tabs, unfortunately the parts I am describing
have a heat slug under the part and are designed to be soldered to the
PCB. Once the parts are soldered down, there is no access to the heat
tab, thermal dissapation is only thru the PCB.
