resulting in a die-junction temperature of approximately 75
°
C which is well within the
maximum operating temperature of the component.
Other heat sinks offered by Chip Coolers, IERC, Thermalloy, Wakefield Engineering and
Aavid Engineering offer different heat sink-to-ambient thermal resistances and may or
may not need air flow.
Though the die junction-to-ambient and the heat sink-to-ambient thermal resistances
are a common figure of merit used for comparing the thermal performance of various
microelectronic packaging technologies, one should exercise caution when only using
this metric in determining thermal management because no single parameter can ade-
quately describe three-dimensional heat flow. The final die-junction operating
temperature is not only a function of the component-level thermal resistance, but of the
system-level design and its operating conditions. In addition to the component's power
consumption, a number of factors affect the final operating die-junction temperature –
airflow, board population (local heat flux of adjacent components), heat sink efficiency,
heat sink attach, heat sink placement, next-level interconnect technology, system air
temperature rise, altitude, etc.
