Abstract
A burn-in oven is provided with a wall that has a number of vertically stacked, laterally extending slots aligned with each of the burn-in-board supports in the oven. When a burn-in-board is placed in the oven on the supports, an edge portion of the burn-in-board extends through a slot into a connector area. Each of the slots has a shutter associated therewith that will move from an open position to permit the burn-in-board connector portion to extend through the slot, to a closed position wherein the shutter covers the slot. A cam operator moves the shutters to a closed position, except when a burn-in-board is extending through a particular slot, it will support the shutter in its open position and the shutter will not be moved by the cam. All the shutters associated with openings through which no burn-in-board connector portion extends will be closed to prevent air flow from the burn-in oven.
