摘要： An infrared soldering machine has an inert gas atmosphere to prevent oxidation of the solder. Heaters positioned within the machine housing above a conveyor has through apertures and fans direct inert gas down through the heaters onto the conveyor. The forced convection assists in maintaining uniform temperature across the conveyor. In order to prevent leakage of ambient air into the housing where the fan shafts protrude for connection to electric motors, a gas seal is provided at each fan shaft. The seal extends between two spaced bearings rotatably securing the fan shaft. Each electric motor is mounted away from the heat of the machine and is connected to the respective fan shaft by means of a belt drive.

摘要： 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.

摘要： 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.

摘要： A solder wave nozzle construction allows components to be disassembled for cleaning and removing dross from a solder reservoir. The quick connection joints allow downtime for cleaning a solder wave machine to be greatly reduced. In one embodiment a solder nozzle duct fits over a chimney flow duct and has quick release clips on each side. In another embodiment, a quick release back plate, front plate, exit trough, dross reduction tray and front gate are all easily removable. In a further embodiment a solder nozzle duct fits within a chimney flow duct, and has an adjustable height so it can be positioned for optimum solder wave height.
