Abstract:
A system for concurrent testing a plurality of integrated circuits (""ICs"") under elevated temperatures comprising:an oven;a burn-in board enclosed in the oven and coupled to the oven and containing the ICs;a driver/interface board coupled to the burn-in board for transferring signals to and from the burn-in board;a computer coupled to the driver/interface board for controlling a burn-in test of the ICs;a switch module on the burn-in board for transferring signals to be written to the ICs that cause the ICs to perform intended functions and for transferring signals read from the ICs that indicate whether the intended functions were performed, the switch module comprising:a plurality of signal inputs;a plurality of high order signal outputs;a plurality of low order signal outputs;a first set of switches for connecting the plurality of signal inputs to the plurality of high order signal outputs;a second set of switches for connecting the plurality of signal inputs to the plurality of low order signal outputs, wherein the first and the second set of switches are capable of operating at temperatures in excess of 150 degrees Celsius.
