Abstract

A burn-in testing system for evaluating a circuit under test, the system including a burn-in board having a plurality of receptacles, at least one of which being sized to receive the circuit under test, test interface circuitry supported by the board and coupled to the receptacles, the test interface circuitry including a transmitter and receiver; power conductors supported by the board, coupled to the receptacles and configured to be connected to a power supply to power the circuit under test during burn-in testing, control and data signal conductors, a burn-in oven having a compartment selectively receiving the burn-in board and being configured to apply heat within the compartment, and an interrogator unit supported by the burn-in oven, the interrogator unit being configured to send commands to the test interface circuitry to exercise the circuit under test optically or via radio communication and to receive responses to the commands optically or via radio communication. A method for testing an integrated circuit having operational circuitry formed thereon, optically and via radio frequency.
