  • Method and apparatus for controlling a time/temperature profile of a reflow oven
    Patent number: 6168064
    Abstract: The present invention relates to controls for a multi-zone reflow oven. In the present invention a plurality of infra red thermal scanners are located at critical points along the path which a substrate passes in a reflow oven so as to generate an actual solder paste time/temperature profile as a substrate passes through the zones of the reflow oven. The actual temperature of the solder paste is determined at critical zones for generating feedback control signals. The time/temperature profile is stored for transfer to a different reflow oven so as to effect the identical solder paste time/temperature curve on the same or a different oven.
    Type: Grant
