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 Appendix A
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.
