  • Convection/infrared solder reflow apparatus
    Patent number: 5573688
    Abstract: Apparatus for soldering surface mounted devices to printed circuit boards utilizing a combination of forced convection and infrared radiation. Fans are disposed in each heating zone which force gas through a heating plate which heats the air, emits infrared radiation for heating of printed circuit boards, and establishes a flow pattern for the gas. Flows are controlled in each zone by selectively introducing unheated gas into each zone, and by selectively exhausting gas from each zone. The volume of gas introduced and exhausted from each zone can be controlled. Closures are provided in the return channels to the low pressure side of the fan for controlling the volume of gas recirculated from the conveyor. Flow is controlled such that cooler air is always introduced into the zones which have a lower temperature and is exhausted from zones which have higher temperatures.
    Type: Grant
    Filed: July 5, 1994
    Date of Patent: November 12, 1996
    Assignee: Vitronics Corporation
    Inventors: Albert Chanasyk, Walter J. Hall, J. Robert Maxwell, Russell G. Shaw, Roy J. Palhof, Phillip D. Bourgelais
