ILM Interchangeability

ILM cover assemblies and ILM back plates built from the Intel controlled drawings are
intended to be interchangeable. Interchangeability is defined as an ILM from Vendor A
that will demonstrate acceptable manufacturability and reliability with a socket body
from Vendor A, B, or C. ILM covers assemblies and ILM back plates from all vendors
that are also interchangeable.
The ILMs are an integral part of the socket validation testing. ILMs from each vendor
have been tested with the socket bodies from each of the current vendors. The tests
include manufacturability, bake and thermal cycling.
See Appendix A
Note: Desktop and Server ILM backplate/screws are NOT interchangeable.
Note: ILMs that are not compliant with 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.
