Integrated Stackup Height (mm)
From Top of Board to Top of IHS
Notes:
1. This data is provided for information only, and should be derived from: (a) the height of the socket seating
plane above the motherboard after reflow, given in
package seating plane to the top of the IHS, and accounting for its nominal variation and tolerances that
are given in the corresponding processor datasheet.
2. This value is a RSS calculation.

Socket Maximum Temperature

The power dissipated within the socket is a function of the current at the pin level and
the effective pin resistance. To ensure socket long term reliability, Intel defines socket
maximum temperature using a via on the underside of the motherboard. Exceeding the
temperature guidance may result in socket body deformation, or increases in thermal
and electrical resistance which can cause a thermal runaway and eventual electrical
failure. The guidance for socket maximum temperature is listed below:
• Via temperature under socket < 96 °C
