Abstract:
1. An IC current measuring apparatus for measuring current flowing through a plurality of terminals of an IC while being connected between the IC and a substrate, the IC current measuring apparatus comprising: a plurality of IC-facing terminals each to be connected to a different one of the plurality of terminals of the IC; a plurality of substrate-facing terminals each (i) to be connected to a different one of a plurality of terminals of the substrate and (ii) electrically connected to a different one of the plurality of IC-facing terminals; a first element to generate a voltage in accordance with current flowing between a first IC-facing terminal and one of the plurality of substrate-facing terminals that corresponds to the first IC-facing terminal, the first IC-facing terminal being one of the plurality of IC-facing terminals; a second element to generate a voltage in accordance with current flowing between a second IC-facing terminal and one of the plurality of substrate-facing terminals that corresponds to the second IC-facing terminal, the second IC-facing terminal being one of the plurality of IC-facing terminals; a first lead-out terminal to output the voltage generated by the first element to the outside, the voltage indicating a potential difference between the first IC-facing terminal and the one of the plurality of substrate-facing terminals corresponding to the first IC-facing terminal; and a second lead-out terminal to output the voltage generated by the second element to the outside, the voltage indicating a potential difference between the second IC-facing terminal and the one of the plurality of substrate-facing terminals corresponding to the second IC-facing terminal.
