A burn-in apparatus for burning-in or testing at least one device-under-test (DUT) that is mounted on a burn-in-board comprising a chamber, a board support affixed within the chamber so as to support a burn-in board in an installed position, a blower for creating a circulating gas flow in the chamber, a heat exchanger that removes heat generated during burn-in, and at least one gas flow linearizer upstream of the board support in the circulating gas flow. The linearizer has a first axis substantially parallel to the circulating gas flow and is at least of sufficient length in the direction of the first axis to substantially linearize the circulating gas flow in the vicinity of the installed burn-in board. |
