METHOD FOR REMOVING FUME IN REFLOW FURNACE AND REFLOW FURNACE |
摘要 |
In a conventional reflow furnace equipped with a fume removal device, fume solids adhere to the inside of piping connecting it to the removal device, and a great amount of trouble was required for removal of the fume solids. The present invention maintains a fumes-containing gas discharged from a furnace at a temperature of at least the liquefication temperature of the fumes until the gas reaches a removal device so that fume solids do not adhere to the inside of piping. A removal device installed on a reflow furnace according to the present invention comprises an elongated-hole filter and a labyrinth filter, and fumes are completely removed by both filters.
