METHOD FOR REMOVING FUME IN REFLOW FURNACE AND REFLOW FURNACE

摘要

[PROBLEMS] A reflow furnace having a conventional apparatus for removing fume has required much work for removing solids resulting from fume being attached to the inside of a piping connected to the above apparatus. [MEANS FOR SOLVING PROBLEMS] A reflow furnace of the present invention has a structure wherein a gas containing fume from the furnace maintains a temperature of a liquefying temperature of the fume or higher until the gas reaches an apparatus for removing fume, which results in the absence of solids attached to the inside of the above piping. An apparatus for removing fume provided in the reflow furnace of the present invention comprises a long hole filter and a filter of a maze form, and can remove fume perfectly by the use of the above both filters.
