    摘要: The present invention provides a chip resistor and a method of making the same for alleviating stress resulted from thermal expansion difference and thus suppressing cracks. A chip resistor includes: a substrate, having a carrying surface and a mounting surface facing away from each other; a pair of upper electrodes, disposed at two ends of the carrying surface; a resistor, disposed on the carrying surface and between the pair of upper electrodes, and electrically connected to the pair of upper electrodes; a stress relaxation layer having flexibility and formed on the mounting surface of the substrate; a metal thin film layer, formed on a surface of the stress relaxation layer opposite to the substrate; a side electrode for electrically connecting the upper electrodes and the metal thin film layer; and a plating layer covering the side electrode and the metal thin film layer.

    摘要: A metal strip resistor is provided. The metal strip resistor includes a metal strip forming a resistive element and providing support for the metal strip resistor without use of a separate substrate. There are first and second opposite terminations overlaying the metal strip. There is plating on each of the first and second opposite terminations. There is also an insulating material overlaying the metal strip between the first and second opposite terminations. A method for forming a metal strip resistor wherein a metal strip provides support for the metal strip resistor without use of a separate substrate is provided. The method includes coating an insulative material to the metal strip, applying a lithographic process to form a conductive pattern overlaying the resistive material wherein the conductive pattern includes first and second opposite terminations, electroplating the conductive pattern, and adjusting resistance of the metal strip.
