Height Restrictions
Figure 20 shows the mechanical stack-up and the associated component clearance requirements.
This is the module keep-out zone and should not be entered. The system manufacturer establishes
board-to-board clearance between the module and the system electronics by selecting one of three
mating connectors available in heights of approximately 4 mm, 6 mm, and 8 mm. The three sizes
provide flexibility in choosing the system electronics components between the two boards.
Information on these connectors can be obtained from your Intel sales representative.

Thermal Transfer Plate
The thermal transfer plates (TTP) provide heat dissipation on the mobile Pentium III processor and
the 82443BX. The TTP may vary on different generations of Intel mobile modules. The TTP
provides the thermal attach point, where a system manufacturer can transfer heat through the
notebook system using a heat pipe, a heat spreader plate, or a thermal solution. Attachment
dimensions for the thermal interface block to the TTP are provided in Figure 21, Figure 22, and
Figure 23. The TTP on the mobile module is designed to be a high efficiency spreader. To fully
take advantage of the mobile module thermal design and optimize the system thermal performance,
the contact area (Ac) needs to be a minimum of 30 mm x 30 mm. While it crucial to maximize the
contact area, it is equally important to ensure that the contact area and/or the mobile module is free
from warpage in an assembled configuration.
Warning:
If warpage occurs, the thermal resistance of the mobile module could be adversely affected.
When attaching a mating block to either TTP, Intel recommends that a thermal elastomer be used as
an interface material. This material reduces the thermal resistance. The OEM thermal interface
block should be secured to the CPU TTP with M2 screws using a maximum torque of 1.5 Kg*cm
to 2.0 Kg*cm (equivalent to 0.147 N*m to.197 N*m). The thread length of the M2 screws should
