  • Temperature sensor manufacturing process
    Patent number: 6225141
    Abstract: The present method defines a plurality of individual temperature sensor cells on a single printed circuit board with a separate temperature detector mounted in each cell. The temperature response of each detector is characterized substantially simultaneously and the values for series and parallel trimmer resistors for each cell are determined from the temperature response of the detector for the cell. Then an automated machine attaches properly valued resistors in parallel and in series with each detector on the printed circuit board.
