ABSTRACT:
A socket connector includes an insulative body defining a number of chambers each retaining a contact element. The chambers receive solder balls of an integrated circuit (IC) module therein to form electrical engagement between each contact element and the corresponding solder ball of the IC module. The contact element has a trifurcated end including a central branch and two side branches which are bent in opposite directions thereby defining a space therebetween for receiving and securely retaining the solder ball. The side branches are spaced from each other for partially receiving the solder ball therebetween. Each side branch has a sharp edge that cuts through an oxidation layer formed on the solder ball thereby eliminating high impedance caused by the oxidation layer.
