Abstract

A measuring device is provided: the measuring device including: a power supply configured to provide electric power to a chip via at least one of a chip connection and a chip-carrier connection; a chip arrangement receiving portion configured to receive a chip arrangement, the chip arrangement including a chip and a chip-carrier connected to the chip via one or more chip-to-chip-carrier connections; a detection portion including a plate; a detection circuit coupled to the plate and configured to detect an electrical signal from the plate; wherein the plate is configured such that it covers at least part of at least one of the chip, the chip-carrier, and the chip-to-chip-carrier connection; and wherein the plate is further configured such that at least part of the at least one of the chip, the chip-carrier, and the chip-to-chip-carrier connection is uncovered by the plate.
