Independent Loading Mechanism (ILM)Interchangeability
ILM assembly and ILM back plate built from the Intel controlled drawings are intended
to be interchangeable. Interchangeability is defined as an ILM from Vendor A will
demonstrate acceptable manufacturability and reliability with a socket body from
Vendor A, B or C. ILM assembly and ILM back plate from all vendors are also
interchangeable.
The ILM are an integral part of the socket validation testing. ILMs from each vendor
will be matrix tested with the socket bodies from each of the current vendors. The
tests would include: manufacturability, bake and thermal cycling.
See Component Suppliers on page 28 for vendor part numbers that were tested.
Note: ILMs that are not compliant to the Intel controlled ILM drawings can not be assured to
be interchangeable.
Markings
There are four markings on the ILM:
• 115XLM: Font type is Helvetica Bold - minimum 6 point (2.125 mm).
• Manufacturer's insignia (font size at supplier's discretion).
• Lot identification code (allows traceability of manufacturing date and location).
• Pin 1 indicator on the load plate.
All markings must be visible after the ILM is assembled on the motherboard.
115XLM and the manufacturer's insignia can be ink stamped or laser marked on the
side wall.
Independent Loading Mechanism (ILM) Cover
Intel has developed an ILM Cover that will snap onto the ILM for the LGA115x socket
family. The ILM cover is intended to reduce the potential for socket contact damage
from operator and customer fingers being close to the socket contacts to remove or
install the pick and place cap. The ILM Cover concept is shown in Figure 11 on page
22.
The ILM Cover is intended to be used in place of the pick and place cover once the ILM
is assembled to the motherboard. The ILM will be offered with the ILM Cover pre-
assembled as well as offered as a discrete component.
ILM Cover features:
• Pre-assembled by the ILM vendors to the ILM load plate. It will also be offered as
a discrete component.
• The ILM cover will pop off if a processor is installed in the socket, and the ILM
Cover and ILM are from the same manufacturer.
• ILM Cover can be installed while the ILM is open.
• Maintain inter-changeability between validated ILM vendors for LGA115x socket,
with the exception noted below.
