Abstract
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.
