<p>PURPOSE:To decrease the consumption of inert gas and reduce the floor space for a silver paste curing device by a method wherein curing units are stacked up vertically, and a cover is provided, surrounding the curing units. CONSTITUTION:Heaters 1 used for curing lead frames 5 are stacked up vertically. That is, a piping 3 is arranged above the heater 1 to blow inert gas of nitrogen against the lead frame 5, and the heaters 1 are surrounded in a cover 4a, including the other component parts. Furthermore, a port opening 7 through which the lead frames 5 are taken in and out is provided to the undermost part of the cover 4a, facing down. As the heaters 1 are stacked vertically, a silver paste curing device of this design requires less floor space. The cover 4a extends high in a vertical direction, so that the consumption of inert gas can be lessened as much as possible.</p> |
