REFLOW FURNACE, DEVICE FOR CONTROLLING OXYGEN CONCENTRATION, METHOD FOR CONTROLLING OXYGEN CONCENTRATION IN FURNACE, PROGRAM FOR CONTROLLING OXYGEN CONCENTRATION, AND RECORDING MEDIUM STORING PROGRAM FOR CONTROLLING OXYGEN CONCENTRATION

摘要

PROBLEM TO BE SOLVED: To provide a reflow furnace capable of reducing the supply cost of an inactive gas.;SOLUTION: The reflow furnace 105 soldering a part on a printed-circuit board 30 contains a control section 20 inputting the state of a solder material from a solder material state detector detecting the state of the solder material related to a soldering. The control section 20 controls valves 14 and 15 in response to the input solder material state and controls an oxygen concentration in the furnace.;COPYRIGHT: (C)2008,JPO&INPIT
