Abstract

PURPOSE:To shorten the time of free air cooling after the reducing process, to prevent the decline of the effect of reduction, and to improve the yield of product, by employing the continuous conveyor for processing the reduction and soldering in the assembly work of the semiconductor unit, etc. CONSTITUTION:The conveyor chain 1 is traveled, the stem 3 is supplied by the loader A, and the pellet 8 is placed on the stem 3. These are inserted into the reducing furnace B with the travel of the chain 1 on purpose to clean the surface of the stem 3 and the collector face of the pellet 8. At the stage of exposure to the air before entering into the soldering furnace C for the next step, the solder is placed on the stem 3, and the pellet 8 is located on this solder. Then, the stem 3 is joined to the pellet 8 in the soldering furnace C. At this process, the time of period from the outlet of reducing furnace B to the solder placing is about 2-3 minutes, so that the surface of stem 3 and pellet 8 is hardly oxidized and the wettability of solder is good. The soldered portion is cooled and fixed, and then, is conveyed to next process through the unloader D.
