ABSTRACT:
Chip carrier socket has contact terminals therein comprising a web portion and first and second arms extending from the web. The first arm has a contact portion adjacent its free end for contacting a pad on a chip carrier and the second arm has a bearing portion adjacent to its free end. The intermediate portion of the second arm is not supported against wall surfaces of the chip carrier socket. The web is connected to a mounting portion by a neck which is compliantly responsive to stressing of the arms. When the contact portion engages a contact pad on a chip carrier, the entire system including the first and second arms and the web is stressed. The second arm is flexed and the freely supported end of the second arm is moved along its fixed support surface. The design permits the achievement of a high contact force and is capable of accommodating manufacturing tolerances in the chip carrier while maintaining the required contact force.
