3. MECHANICAL REQUIREMENTS
3.1. Pin-Out and Orientation Diagram:
The pin-out for the 423 pin socket is shown in Figure 3. This diagram is viewed from
the TOP of the SOCKET. The socket dimensions, the tab and stopper details are
provided in Figure 4, Figure 5, and Figure 6.
3.2. Mechanical Supports:
Socket tabs shall be used with a heat sink clip to isolate the mass of the package and
the associated heat sink from the socket during the shock and vibration conditions
outlined in Sections 5.3 and 5.4. The socket must pass the mechanical shock and
vibration requirements listed in Sections 5.3 and 5.4 with the associated mass of
300g (max) for socket attach, and 450g (max) for retention module support.
