ABSTRACT:
A burn-in apparatus for conducting a burn-in test by housing a burn-in board mounted with a large number of DUT in a burn-in chamber, moving a temperature adjustment board downward and bringing temperature adjustment arrays attached to the temperature adjustment board contact with corresponding DUT; comprising a push-pull device having a movable body moving back and forth in the horizontal direction of a board surface of the burn-in board and a cam mechanism composed of a tilted cam and cam follower for elevating/lowering an elevator board by converting a back-and-forth movement of the movable body to a vertical movement is provided; wherein the push-pull device for elevating/lowering the temperature adjustment board can be downsized, so that a more compact burn-in apparatus can be provided.
