ILM Features
• Allows for topside thermal solution attach to a rigid structure. This eliminates the
motherboard thickness dependency from the mechanical stackup.
• Captive nuts clamp the ILM frame to the board and reduced board bending leading
to higher solder joint reliability.
• ILM levers provide an interlocking mechanism to ensure proper opening or closing
sequence for the operator.
4.2.1
ILM Closing sequence
When closing the ILM, the interlocking features are intended to prevent the hinge lever
from being latched first. If an attempt is made to close the hinge lever first, the hinge
lever end stop will prevent the user from latching the active lever, indicating something
is done wrong. Text on the ILM cover indicates the proper order of operation. Refer to
If hinge lever is pressed down first, it raises the load plate up at an angle higher than
the active lever can make contact with, forcing a user to push it down. Also the hinge
lever end stop will block the active lever from being able to be latched.
