Thermal
The recommended attachment method to the heat sink is illustrated in
printed-circuit board with the spring force centered over the die. This spring force should not exceed 10 pounds force (45
Newton).
The system board designer can choose between several types of heat sinks to place on the device. Ultimately, the final selection
of an appropriate heat sink depends on many factors, such as thermal performance at a given air velocity, spatial volume, mass,
attachment method, assembly, and cost. Several heat sinks offered by Aavid Thermalloy, Advanced Thermal Solutions, Alpha
Novatech, IERC, Chip Coolers, Millennium Electronics, and Wakefield Engineering offer different heat sink-to-ambient
thermal resistances, that will allow the MPC8535E to function in various environments.
