THICKNESS
Figure 7 shows the Intel Mobile Module profile and
the associated minimum and maximum thickness
of the printed circuit board (PCB). The range of
PCB

technologies to be used with current and future
modules.

NOTE
The system manufacturer must ensure that
the mechanical restraining method and/or
system-level EMI contacts are able to
support this range of PCB thickness, to
ensure compatibility with future modules.
4.1.3.
HEIGHT RESTRICTIONS
Figure 8 shows the Intel Mobile Module
mechanical stackup and associated component
clearance requirements. This "block" represents
the volume that may be occupied by components
on the various versions of the processor module.
The OEM system should be defined so that no part
of the system will intrude into this volume, which
may result in part-to-part interference.
The system manufacturer establishes the board-
to-board clearance between the Intel Mobile
Module and the system electronics by selecting
one of three possible mating connectors. The
mating
connectors
provide
clearance distances of 4 mm, 6 mm or 8 mm. With
these three options, the system manufacturer has
reasonable flexibility in choosing components on
the system electronics that are between the two
boards.
board-to-board
NOTE
The Intel Mobile Module top side component
clearance is referenced from the bottom of the
PCB, so it is independent of the PCB thickness.
Figure 8 shows the module volume assuming a
4mm board-to-board connector. When using the
4mm connector, 2mm of the connector height
extends beyond the module volume shown in
figure 8. If the 6mm board-to-board connector is
used on the system electronics, then 4mm extends
beyond the module
“keep-out” volume. If using the
8mm connector, 6mm will extend beyond the
module “keep-out” volume.
