  • Patent number: 8878559
    Abstract: An IC current measuring apparatus is provided between an IC and a substrate. The IC current measuring apparatus electrically connects each of a plurality of IC-facing terminals and a different one of a plurality of substrate-facing terminals. Especially, resistances are each inserted into a path between an IC terminal targeted for measurement and a substrate terminal corresponding thereto. Furthermore, the IC current measuring apparatus is provided with terminals each used to measure a voltage between both ends of an inserted resistance corresponding thereto. Accordingly, a measurer who measures current flowing through an IC-facing terminal can measure the current flowing through the IC-facing terminal by providing the IC current measuring apparatus between the IC targeted for measurement and the substrate and measuring a voltage between both ends of an inserted resistance corresponding to the IC terminal through which current he/she wishes to measure flows.
