  • Gas knife cooling system
    Patent number: 5577658
    Abstract: A gas knife cooling system for reflow soldering cools soldered articles by impinging a gas flow directly on the articles and as a result uses less cooling gas. A heater is associated with the cooling system to remove flux deposits. The cooling system is installed in the cooling section of a reflow soldering apparatus and comprises at least one gas knife to direct a gas stream at soldered products passing through the cooling section on a conveyor. A heater is associated with the gas knife which is activated for predetermined cleaning cycles to heat the gas knife to a temperature above flux vaporization temperature of flux deposits from the soldered products.
