CPU Socket - wikipedia CPU Socket LGA 775, a land grid array socket Socket A ( a.k.a. Socket 462 ) a pin grid array socket In computer hardware, a CPU socket or CPU slot comprises one or more mechanical components providing mechanical and electrical connections between a microprocessor and a printed circuit board ( PCB ). This allows for placing and replacing the central processing unit ( CPU ) without soldering. Common sockets have retention clips that apply a constant force, which must be overcome when a device is inserted. For chips with a large number of pins, zero insertion force ( ZIF ) sockets are preferred. Common sockets include Pin Grid Array ( PGA ) or Land Grid Array ( LGA ). These designs apply a compression force once either a handle ( PGA type ) or a surface plate ( LGA type ) is put into place. This provides superior mechanical retention while avoiding the risk of bending pins when inserting the chip into the socket. Certain devices use Ball Grid Array ( BGA ) sockets, although these require soldering and are generally not considered user replaceable. CPU sockets are used on the motherboard in desktop and server computers. Because they allow easy swapping of components, they are also used for prototyping new circuits. Laptops typically use surface - mount CPUs, which take up less space on the motherboard than a socketed part.

Other types used include PLCC and CLCC sockets. Function A CPU socket is made of plastic, and often comes with a lever or latch, and with metal contacts for each of the pins or lands on the CPU. Many packages are keyed to ensure the proper insertion of the CPU. CPUs with a PGA ( pin grid array ) package are inserted into the socket and, if included, the latch is closed. CPUs with an LGA ( land grid array ) package are inserted into the socket, the latch plate is flipped into 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 a good connection, as well as increased mechanical stability.
