摘要： Flux management systems and methods are provided for filtering vaporized flux from the gas of a reflow soldering oven. A flux management system includes a cooling chamber having a cooling medium through which the gas passes. The vaporized flux condenses on the surfaces of the cooling chamber and drips into a collection pan, thereby preventing it from dripping onto circuit boards passing through the oven. The flux management system may further include a self-cleaning feature that includes a compressed gas, which is allowed to enter the cooling chamber through a solenoid valve. The compressed gas may then be directed through a heater, which increases the temperature of the cooling chamber, thereby causing a decrease in viscosity of the flux, which allows it to flow freely into a drain tube. The flux may then be transported by gravity into a collection container.
