18 Thermal Management
Although provision is made to attach DC fans to the SMT148FX (powered directly
from the input voltage), correct enclosure air flow should be ensured.
Sundance are able to provide a heat-pipe type thermal management solution for two
TIM sites (sites 2 and 3). This involves increased height TIM and RSL connectors for
these sites, the fixing of the heat-pipe system direct to the TIMs’ components, and
the addition of an off-board heatsink and fan. Please consult Sundance for pricing
and availability for this option.
Several components in both the onboard 3.3V and 5.0V supplies are rated at 125
°C
maximum. Without adequate cooling, the inductors in this circuit can reach in
excess of 170
°C when running at full rated load.
Some of the major components are located on the underside of the
carrier board. This will allow heatsinks (or indeed an enclosure) to be
fitted.
