  • Patent number: 4973244
    Abstract: Printed circuit boards, assemblies and the like are heated uniformly from edge to edge or to a desired lateral temperature profile while being conveyed through a heating area. The conveying systems reliably conveys circuit boards and the like through the heating area without dropping them. A rail heater is provided to heat rails supporting conveyors having pins to hold circuit boards and the like. A control for the rail heaters controls the temperature of the rails so the circuit boards are positively supported on the conveyors and have a uniform temperature profile or desired temperature profile from edge to edge.
    Type: Grant

  • Patent number: 4912857
    Abstract: A cooling and exhaust unit for an IR reflow soldering machine is arranged to be mounted on the soldering machine after the last heating zone. The unit has fans which direct cold air downwardly on to the conveyor and this cooling air divides into two streams, one moving with the conveyor and one counter to the movement of the conveyor. An exhaust inlet is provided near the front and the rear of the machine, the exhaust inlets being connected through an exhaust chamber to an exhaust outlet. To minimize the amount of hot process air sucked out of the soldering machine into the nearer exhaust inlet an additional cold air inlet is provided, this being located intermediate the rear end of the unit (i.e., the end abutting the soldering machine) and the nearer exhaust inlet.
