2.10.2 I/O Shield
The back panel I/O shield for the board must meet specific dimension and material requirements.
Systems based on this board need the back panel I/O shield to pass emissions (EMI) certification
testing. Figure 14 shows the critical dimensions of the chassis-independent I/O shield.
Dimensions are given in inches and [millimeters]. The figure indicates the position of each cutout.
Additional design considerations for I/O shields relative to chassis requirements are described in
the microATX specification.
NOTE
A chassis-independent I/O shield designed to be compliant with the microATX chassis specification
is available from Intel. The actual punchouts may differ depending on the board manufacturing
options.
