4 Electrical Requirements
Socket electrical requirements are measured from the socked-seating plane of the processor test
vehicle (PTV) to the component side of the socket PCB to which it is attached. All specification are
maximum values (unless otherwise stated) for a single socket pin, but includes effects of adjacent
pins where indicated. Pin and socket inductance includes exposed pin from mated contact to bottom
of the processor pin field.
