  • Resistance element with improved linearity and method of making the same
    Patent number: 4032881
    Abstract: A highly accurate resistance element formed by depositing a plurality of conductive pads at spaced intervals along a substrate, depositing the resistance element in intimate electrical contact with the pads, sensing the electrical resistance between successive pairs of pads, and trimming away resistance material from the element between selected pairs of pads until predetermined resistance values between each pair are achieved. In a preferred embodiment a portion of each pad is offset from the resistance element and adapted to receive a probe from a laser trimmer. The element can be advantageously employed in potentiometers.
