METHOD FOR CONTROLLING IC HANDLER AND CONTROL SYSTEM USING THE SAME

摘要

The step of comparing the pushing pressure developing when the pusher (8) of a test hand (1) presses an IC (5) placed on the socket (2) with the allowable press force calculated from the combined spring constant for the socket (2) and IC (5), and the step of controlling the operation of the test hand (1) at a pressure equal to or lower than the allowable press force on the basis of the result of the comparison are provided. <IMAGE>
