Abstract:
A system for testing integrated circuit devices and controlling and monitoring said integrated circuit devices-under tests (DUTs), comprising:a test chamber for creating stress conditions to test DUTs;a chamber controller communicatively connected to said test chamber for controlling stress conditions in said test chamber in response to chamber control signals, said chamber controller comprising a temperature controller for modifying the temperature in said test chamber and a chamber interface controller for controlling the electromagnetic field level in said test chamber;a DUT board having one or more DUTs disposed thereon;a driver card communicatively connected to said DUT board for operating and monitoring said DUTs on said DUT board;an adjustable power supply;a power supply controller for controlling power from said adjustable power supply to said driver card and to said DUT board;a computer for providing control signals to said chamber controller, said power supply controller, and said driver card in operating said test chamber and said DUTs and in monitoring the performance of said DUTs; andwhereby said computer operates said chamber controller to dynamically vary the temperature and control the electromagnetic field in said test chamber and generates signals to said DUTs to test and monitor said DUTs.
