LGA1356 Socket, ILM and Back Plate Electrical, Mechanical, and Environmental Specifications

Environmental Requirements
The reliability targets in this chapter are based on the expected field use environment
for these products. The test sequence for the LGA1356 socket was developed using the
knowledge-based reliability evaluation methodology, which is acceleration factor
dependent. A simplified process flow of this methodology can be seen in
.
Since the LGA1356 socket is very similar to the LGA1366 socket, the LGA1356 socket is
expected to perform similarly and full validation for the LGA1356 socket is avoided.

Electrical Requirements for LGA1356 Socket
Parameter
Value
Comment
Mated loop inductance, Loop
<3.9 nH
The inductance calculated for two contacts,
considering one forward conductor and one return
conductor. These values must be satisfied at the
worst-case height of the socket.
Maximum mutual capacitance, C.
<1 pF
The capacitance between two contacts
Socket Average Contact Resistance
(EOL)
15.2 m
Ω
The socket average contact resistance target is
derived from average of every chain contact
resistance for each part used in testing, with a
chain contact resistance defined as the resistance
of each chain minus resistance of shorting bars
divided by number of lands in the daisy chain.
The specification listed is at room temperature
and has to be satisfied at all time.
Socket Contact Resistance:
The resistance of
the socket contact, solderball, and interface
resistance to the interposer land.
Max Individual Contact Resistance
(EOL)
≤
100 m
Ω
The specification listed is at room temperature
and has to be satisfied at all time.
Socket Contact Resistance:
The resistance of
the socket contact, solderball, and interface
resistance to the interposer land; gaps included.
Bulk Resistance Increase
≤
3
m
Ω
The bulk resistance increase per contact from
24 °C to 107 °C
Dielectric Withstand Voltage
360 Volts RMS
Insulation Resistance
800 M
Ω
