Abstract: A ZIF PGA socket of the present invention comprises a base, a cover slidably mounted on the base, a plurality of electrical contacts mounted in the base, a ring insert molded in the cover, and a cam actuator partially received in the ring. The cam actuator comprises a lateral protrusion on an upper lateral side thereof for engaging with one of a pair of flushed stop surfaces on upper sections of the cover and of the ring to determine a respective stop position thereof.

Abstract: A socket for interconnecting a PGA package with a circuit board comprises a base, a cover slidably attached to the base, and supporting means downwardly extending from the base. The base comprises a pair of extension plates diagonally extending therefrom. The supporting means in the form of a pair of standoffs is formed on the respective extension plates. Since each standoff has a height slightly smaller than that of solder balls formed on a lower surface of the base, the standoffs rest on the circuit board after the socket is soldered thereto. By such a design, the external force employed to actuate the cover to slide along the base is transferred from the base to the standoffs. Hence, deformation of the base and damage to the solder joint are obviated to ensure a reliable connection between the PGA package and the circuit board.
