    摘要： The present invention provides a reflow apparatus capable of precisely adjusting the heating temperature and heating time when heating a work for reflow. A work transfer conveyor for transferring a work into a furnace body is disposed, wherein a plurality of preheating zones through for preheating the work, a plurality of reflow zones for heating the work for reflow, and a plurality of cooling zones for cooling the work are successively arranged along the work transfer conveyor in the furnace body. The individual reflow zones are formed shorter than the individual preheating zones in the work transfer direction. It is preferable that the sizes of the individual reflow zones in the transfer direction are shortened to approximately 65% to 85% with respect to the individual preheating zones or the conventional individual reflow zones.
