PROBLEM TO BE SOLVED: To solve the problems that, by the ununiformity of the wind velocity of hot air stirred by the inhalation and exhaust of a circulation fan motor, the drift of the hot air by an air pocket occurs at the inside of a furnace, and that there occurs fine packaging misregistration in an electronic component on the object to be soldered by the nonuniformity of the wind velocity. SOLUTION: In the method for fluidizing hot air at the inside of the furnace in the device where hot air at the inside of a furnace is fluidized, the object to be soldered introduced into the furnace is brought into contact with the fluidized hot air to melt solder on the object to be soldered, and further, an electronic component packaged on the object to be soldered is soldered to the object to be soldered, a nozzle communicated with the pressure feed device provided at the outside of the furnace, and a reflector repelling injected gas from the nozzle to the hot air at the inside of the furnace are arranged, so that gas is blown on the inside of the furnace under pressure to be fluidized.
