Abstract
An electrical connector (4) electrically connects a CPU (6) to a motherboard (3) and comprises a housing (40) and a plurality of contacts (5). The housing has a first face (41) for engaging the CPU, a second face (42) for attaching to the motherboard and a plurality of contact passageways (43) defined between the two faces for receiving the contacts. Each contact comprises a contact section (51) which extends beyond the first face and engages a corresponding contact of the CPU, a tail (52) received in the contact passageway, and a receiving section (53) opposite the contact section which abuts a mating face (44) of the passageway proximate to the second surface to form an arcuate receiving surface for engaging a solder ball (2). After the solder ball is heated, the tail is electrically engaged to a contact on the motherboard. Due to the configuration of the arcuate receiving space, the solder ball remains in its original position and the contact is prevented from inclining.
