NOTES:
1
SOCKET CENTER PLANES ARE REFERENCED FROM GEOMETRIC
CENTER OF SOCKET HOUSING CAVITY FOR CPU PACKAGE (ALIGNS 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 ILM 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. 4.DIMENSIONS ARE IN MILLIMETERS
