  • Publication number: 20210339330
    Abstract: The present application relates to a gas control system and method for a reflow soldering furnace, comprising: an oxygen detecting device, capable of coming into contact with a gas in a furnace chamber, for detecting an oxygen concentration in the furnace chamber; an intake valve device, for controllably establishing fluid communication between a working gas source and the furnace chamber, thereby inputting the working gas into the furnace chamber; and a controller, for controlling the opening extent of at least one intake valve device based on an oxygen concentration signal, thereby regulating a flow rate of the working gas inputted into the furnace chamber.
