Abstract: A socket assembly includes a housing with a plurality of through openings that extend between opposite surfaces of the housing. First and second plurality of contact members are positioned in a plurality of the through openings. The contact members each include major beams and minor beams with proximal ends attached to a center portion, and distal ends extending away from the center portion. The major beams preferably have a length greater than the minor beams. When the first circuit member is engaged with the socket assembly the ball grid array displaces the distal ends of the major beams to create a plurality of first and second forces. The first plurality of forces generally oppose the second plurality of forces. The first and second plurality of forces also generate an engagement force that biases the first circuit member toward the housing. The minor beams on the first and second plurality of contact members do not contribute to the engagement force.

Abstract: An electrical interconnect assembly for electrically interconnecting terminals on a first circuit member with terminals on a second circuit member. The electrical interconnect assembly includes a housing having a plurality of through openings extending between a first surface and a second surface. A plurality of contact members are positioned in a plurality of the through openings. The contact members include a base portion and one or more beams. A layer is molded to the housing and the contact members to retain the contact members in the openings. A solder member is preferably coupled with an engagement feature on the base portion of the contact member.

The electrical interconnect assembly includes a housing having a plurality of through openings extending between a first surface and a second surface. A plurality of electrical contact member are positioned in a plurality of the through openings. The contact members have at least one engagement feature forming a snap-fit relationship with the housing. A stabilizing structure on the housing limits deflection of the contact members in at least one direction.

The electrical interconnect assembly includes a housing having a plurality of through openings extending between a first surface and a second surface. A plurality of contact members are positioned in a plurality of the through openings. The contact members include a base portion, a first beam having a proximal end attached to the base portion and a distal end extending away from the base portion in a first direction, and a second beam having a proximal end attached to the base portion and a distal end extending away from the base portion generally in the first direction. The first and second beams are configured to form at least one loop. At least one tab is attached to the base portion. The tab includes at least one engagement feature mechanically coupled to a solder member.
