3.6.2 Mounting Screw Clearance

CAUTION

The printed circuit board assembly (PCBA) is very close to the mounting holes.
Do not exceed the specified length for the mounting screws. The specified
screw length allows full use of the mounting hole threads while avoiding
damaging or placing unwanted stress on the PCBA.

Figure 3-11 specifies the minimum clearance between the PCBA and the screws
in the mounting holes. The maximum torque applied to the screws must not
exceed 14 inch-pounds (1.57 N-m). A maximum screw length of 0.22 inches
(5.59 mm) may be used in the side mounting locations when a bracket of 0.04
inches (1.016 mm) minimum thickness is used.
