REFLOW APPARATUS

摘要

Provided is a reflow apparatus which can adjust heating temperature and heating time in detail for heating a work for reflow. A work transfer conveyer (12) for transferring a work (W) into a furnace (11) is arranged. Along the work transfer conveyer (12), a plurality of preheat zones (13a-13e) for preheating the work (W), a plurality of reflow zones (14a, 14b, 14c) for heating the work (W) for reflow, and a plurality of cooling zones (15a, 15b) for cooling the work (W) are successively arranged in the furnace (11). Each of the reflow zones (14a, 14b, 14c) has a shorter length in a work transfer direction compared with the length of each of the preheat zones (13a-13e) in the work transfer direction. The size of each of the reflow zones (14a, 14b, 14c) in the transfer direction is preferably shortened to substantially 65-85% of each of the preheat zones (13a-13e) or conventional individual reflow zone.
