LGA2011-0 Socket and ILM Electrical, Mechanical, and Environmental Specifications
5.5
Environmental Requirements
Design, including materials, shall be consistent with the manufacture of units that meet
the following environmental reference points.
The reliability targets in this chapter are based on the expected field use environment
for these products. The test sequence for new sockets will be developed using the
knowledge-based reliability evaluation methodology, which is acceleration factor
dependent. A simplified process flow of this methodology can be seen in
.

Maximum Socket Part Average
Resistance (EOL @ 100 °C)
25 m
Ω
This is the maximum allowable part average socket
resistance allowed under all use conditions (EOL and
100°C). This is monitored by measuring the daisy
chain resistance of all socket contacts in series
across the socket and dividing by the number of
contacts measured. The resulting value must be
below 25 m
Ω
at all use conditions (EOL) and elevated
temperature (100 °C).
Maximum Single Pin Resistance
(mean + 4 sigma) (EOL @ 100 °C)
38 m
Ω
This is the maximum validated single contact
resistance on the socket under all use conditions
(EOL) and at elevated temperature (100 °C). This
accounts for resistance variation across the socket.
While it is possible that a single contact may reach a
resistance of 38 m
Ω
, the maximum socket part
average resistance spec insures that all contacts
averaged together will not be higher than 25 m
Ω
Dielectric Withstand Voltage
360 Volts RMS
Insulation Resistance
800 M
Ω
