Disclosed is a socket ( 10 ) including a base ( 12 ), an array of contacts ( 22 ) in columns and rows, a plurality of positioning blocks ( 121 ) between the rows of the contacts of the base. Each of the contacts includes two deflectable contact pieces ( 223 ) at a distal region thereof to capture one ball ( 200 ) of an IC device ( 20 ) in a manner to prevent movement of that ball in a first horizontal direction. Some of the positioning blocks are arranged for preventing movement of balls of the IC device in a second horizontal direction substantially perpendicular to the first horizontal direction. Thus, the IC device may be accurately positioned on the test socket.
