BOARD FOR CHECKING CONNECTION OF WAFER BURN-IN SYSTEM AND CONNECTION CHECKING METHOD USING THE SAME

摘要

PURPOSE: A board for checking the connection of a wafer burn-in system and a connection checking method using the same are provided to be capable of using a variety of load conditions. CONSTITUTION: A board(500) for checking the connection state of a wafer burn-in system is provided with an input connection part connected with each connection pin of a performance measuring board(250), and an input switching part connected with all the connection line of the input connection part for transmitting the current/voltage signal supplied from the performance measuring board by carrying out a switching process. The board further includes a plurality of resistors connected to the input switching part and a plurality of switching parts one-to-one connected with the resistors for switching the flow of the current/voltage signal by using the control signal supplied from a main test apparatus. At this time, the resistors have different resistances, respectively.
