Thermal
Table 71 provides the thermal resistance with heat sink in open flow.
Simulations with heat sinks were done with the package mounted on the 2s2p thermal test board. The
thermal interface material was a typical thermal grease such as Dow Corning 340 or Wakefield 120 grease.
For system thermal modeling, the MPC8544E thermal model without a lid is shown in Figure 60. The
substrate is modeled as a block 29
× 29 × 1.18 mm with an in-plane conductivity of 18.0 W/mK and a
through-plane conductivity of 1.0 W/mK. The solder balls and air are modeled as a single block
29
× 29 × 0.58 mm with an in-plane conductivity of 0.034 W/mK and a through plane conductivity of
12.1 W/mK. The die is modeled as 7.6
× 8.4 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
6.5 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. Please refer to Figure 59 for actual dimensions.
