ABSTRACT:
A baking oven for heating lead frames used in the manufacturing of semiconductor devices including an oven main body having an entrance and an exit for lead frames, a heating device which creates a high-temperature atmosphere inside the oven main body, a lead frame magazine installed inside the oven main body so as to accommodate lead frames in a stacked fashion, a magazine mover which moves the lead frame magazine in a vertical direction, and a width adjustment device that changes the width of the lead frame magazine in a horizontal direction. The magazine mover and the width adjustment device are provided outside the oven main body for securing a high lead frame accommodation capacity and a longer heating time of the oven.
