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.
