CPU socket

In computer hardware, a CPU socket or CPU slot comprises one or moremechanical components providing mechanical and electrical connectionsbetween a microprocessor and a printed circuit board.

Common sockets have retention clips that apply a constant force, which mustbe overcome when a device is inserted.

For chips with a large number of pins, either zero insertion force sockets or landgrid array sockets are used instead. These designs apply a compression forceonce either a handle or a surface plate is put into place.

CPU sockets are used in desktop and server computers.

Laptops typically use surface-mount CPUs, which take up less space than asocketed part.

CPUs with an LGA package are inserted into the socket, the latch plate is flippedinto position atop the CPU, and the lever is lowered and locked into place, pressing the CPU’s contacts firmly against the socket’s lands and ensuring agood connection, as well as increased mechanical stability.
