Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional IC current measuring technologies can only measure the total current flowing through an IC and cannot individually measure current flowing through each terminal of the IC.
Innovation Solution
An IC current measuring apparatus is provided between the IC and a substrate, featuring multiple IC-facing and substrate-facing terminals, resistance elements, and lead-out terminals to measure current flowing through each terminal by generating and outputting voltage corresponding to the current flowing between these terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an ammeter is connected between the IC power source and substrate power source to measure total current, then current measurement capability is provided, but only total current measurement is possible and individual terminal current measurement is not achievable
Solution Approach 1:
The patent divides the single total current measurement function into multiple individual terminal current measurement functions. By inserting separate resistance elements into the current paths of individual terminals and providing separate lead-out terminals for each, the system enables measurement of current at each terminal independently, thus segmenting the measurement capability to achieve both total current and individual terminal current measurements.
2Adaptability or versatility
If multiple resistance elements are inserted into current paths of individual terminals to enable individual terminal current measurement, then measurement scope is improved, but device complexity increases
Solution Approach 1:
The adapter structure serves multiple functions simultaneously: it acts as both a connection interface between IC and substrate and as a measurement device. The resistance elements are integrated into the adapter's current paths, and the lead-out terminals are part of the adapter structure, allowing the same device to both connect and measure without requiring separate measurement equipment.

AI summary
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.
