Abstract: A land grid array (LGA) socket is adapted to receive an IC module (40) and mounted on a PCB (50). The socket (1) includes an insulative housing (30) having a plurality of passageways (302) and a plurality of electrical terminals (10) received in the passageways. Each of the terminals includes a retention portion (12), a pressing arm (16) bent slantwise and extending upwardly from an end of the retention portion, and a contacting arm (18) bent slantwise and extending downwardly from another end of the retention portion.
