Thermal
Millennium Electronics offer different heat sink-to-ambient thermal resistances, that will allow the
MPC8568E to function in various environments.
24.2.1
Recommended Thermal Model
For system thermal modeling, the MPC8568E thermal model without a lid is shown in Figure 70. The
substrate is modeled as a block 33x33x1.18 mm with an in-plane conductivity of 24 W/mK and a
through-plane conductivity of 0.92 W/mK. The solder balls and air are modeled as a single block
33x33x0.58 mm with an in-plane conductivity of 0.034 W/mK and a through plane conductivity of 12.2
W/mK. The die is modeled as 8.2x12.1 mm with a thickness of 0.75 mm. The bump/underfill layer is
modeled as a collapsed thermal resistance between the die and substrate assuming a conductivity of 5.3
W/mK in the thickness dimension of 0.07 mm. The die is centered on the substrate. The thermal model
uses approximate dimensions to reduce grid. See the case outline for actual dimensions.
