    摘要： A resistor and an integrated heat spreader are provided. A resistive element having a first surface is in contact with electrically conducting terminals. A heat spreader is provided having at least a portion in thermally conductive contact with at least a portion of the first surface of the resistive element. The heat spreader comprising a thermally conducting and electrically insulating material, and has terminations, each termination adjacent to one of the electrically conducting terminals. Each termination is in thermally conducting contact with the adjacent electrically conducting terminal. A method of fabricating a resistor and an integrated heat spreader is also provided.

    摘要： 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. For one or more sets of conductive pads, a calculated amount of additional insulative material adjacent the respective conductive pads is removed based upon the preliminary resistance value between the corresponding set of conductive pads and a final resistance value to exposed additional portions of resistive material. The conductive pads and resistive material is cut at substantially the middle of each conductive pad to form pieces. A second set of one or more conductive layers are formed on the first set of one or more conductive layers at opposing ends of each piece, and the additionally exposed portions of the resistive material.
