ABSTRACT:
An IC tester for preventing damage from electrostatic discharge (ESD) and operation method thereof. The IC tester contains a temperature control oven chamber, an oven door connected to the temperature control oven chamber, at least a pair of thermal-isolated bars situated on one side of the oven door, and an actuating bar situated in the oven door. The actuating bar is connected to the thermal-isolated bars for controlling the pair of thermal-isolated bars to open or close. Therefore a DUT board is capable of passing through the pair of thermal-isolated bars for being loaded on the oven door and for not rubbing against the thermal-isolated bars when the pair of thermal-isolated bars is open so as to avoid ESD.
