NOTES:
1 SOCKET CENTER PLANES ARE REFERENCED FROM GEOMETRIC
CENTER OF SOCKET HOUSING CAVITY FOR CPU PACKAGE (ALIGNES
WITH DATUM REFERENCE GIVEN FOR BOARD COMPONENT KEEP-INS).
2 SOCKET KEEP-IN VOLUME VERTICAL HEIGHT ESTABLISHES LIMIT OF SOCKET
AND CPU PACKAGE ASSEMBLY IN THE SOCKET LOCKED DOWN POSITION.
IT ENCOMPASSES SOCKET AND CPU PACKAGE DIMENSIONAL TOLERANCES
AND DEFLECTION / SHAPE CHANGES DUE TO DSL LOAD.
3. SOCKET KEEP-IN VOLUME ENCOMPASS THE SOCKET NOMINAL VOLUME
AND ALLOWANCES FOR SIZE TOLERANCES. THERMAL/MECHANICAL COMPONENT
DEVELOPERS SHALL DESIGN TO THE OUTSIDE OF SOCKET KEEP IN VOLUME WITH
CLEARANCE MARGINS. SOCKET DEVELOPERS SHALL DESIGN TO THE INSIDE VOLUME.
