<P> 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 . </P>
