METHOD FOR MANAGEMENT OF IN-FURNACE ATMOSPHERE OF REFLOW SOLDERING EQUIPMENT AND REFLOW SOLDERING EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a method for management of an in-furnace atmosphere by which the oxygen atmosphere in gaseous nitrogen in a furnace of reflow soldering equipment is kept at a desired value and reflow soldering equipment which realizes the method.;SOLUTION: The reflow soldering equipment which performs reflow soldering within the furnace 1 supplied with the gaseous nitrogen is equipped with: gaseous nitrogen supplying means 8 to 23 capable of supplying the gaseous nitrogen into the furnace 1; a means 24 for detecting the oxygen concentration in the furnace 1; and control means 25 and 26 for controlling the oxygen concentration of the gaseous nitrogen supplied from the gaseous nitrogen supplying means 8 to 23 according to the oxygen concentration in the furnace 1 detected by the detecting means 24.;COPYRIGHT: (C)2005,JPO&NCIPI
