APPARATUS AND METHOD FOR DETECTING A POSITION

摘要

PURPOSE: An apparatus and a method for detecting a position are provided to a time required for the location of a test socket by sensing the position of the test socket based on the position of a corner of an uppers part. CONSTITUTION: A test socket(40) inspects at least semiconductor module(10). The position of the test socket is detected based on the position of the edge of detected top side. A first detector(200) is faced with the top side of the reference block. The first detector detects the position of the edge having a certain distance from the test socket of the top side. The first detector includes a reflection-type photosensor(210) and a transport unit(220) opposite to the top side of the reference block.
