An electrical connector ( 1 ) is used for electrically connecting a ball grid array (BGA) central processing unit (CPU) ( 3 ) with a printed circuit board (PCB). The connector includes a generally rectangular insulative housing ( 10 ) and a number of terminals ( 20 ) received in the housing. Each of the terminals includes a connecting portion ( 200 ), a solder pad ( 202 ) extending from a bottom end of the connecting portion, and a cantilever ( 204 ) extending aslant from a top end of the connecting portion. The cantilever has a concave portion ( 206 ) near a free end thereof. When the CPU with a multiplicity of solder balls is attached onto the connector, the concave portions of the terminals cover bottom portions of the solder balls. Therefore, the terminals of the connector electrically connect with the solder balls of the CPU steadily, and a reliable connection between the CPU and the PCB is established.
