ELECTRIC RESISTANCE MEASURING SHEET, ELECTRIC RESISTANCE MEASURING CONNECTOR DEVICE, AND ELECTRIC RESISTANCE MEASURING DEVICE FOR CIRCUIT BOARD

摘要

PPROBLEM TO BE SOLVED: To provide an electric resistance measuring sheet, an electric resistance measuring connector device, and an electric resistance measuring device for circuit boards capable of achieving a required electric connection even if an inspection object circuit board has many small-size inspection object electrodes, ensuring a long service life for an anisotropically conductive elastomer sheet even if the inspection object electrodes differ in the projection height thereof, and achieving a stable electric connection to all the inspection object electrodes. PSOLUTION: The electric resistance measuring sheet includes a set of connecting electrodes comprising two current supply electrodes and two voltage measuring electrodes disposed on the surface of an insulating sheet, corresponding to the inspection object electrodes, and relay electrodes disposed on the rear surface of the insulating sheet and electrically connected to each one of the current supply electrodes and the voltage measuring electrodes, the relay electrodes being positioned so that they will not overlap the current supply electrodes and the voltage measuring electrodes when seen through in the thickness direction.
