  • Patent number: 9934891
    Abstract: The present technology is directed toward a resistor and method of manufacturing the resistor. One or more layers of insulative material are formed on a length of resistive material. Portions of the one or more layers insulative material are removed from the resistive material in a pattern based on a predetermined approximate dimension and predetermined approximate resistance value. A first set of one or more conductive layers are formed on the portions of the resistive material exposed by the insulative coating to form a plurality of conductive pads on the resistive material between the patterned insulative material. The sets of conductive pads are probed to measure a preliminary resistance value between the sets of conductive pads.
